ACTIVITY GUIDELINES 1. PARTICIPATION: The program is open to all Cheshire youth interested in learning and developing new basketball skills. Students are to participate equally in all phases of the program. 2. SPORTSMANSHIP: Coaches and supervisors should strive to teach sound sportsmanship behavior patterns. 3. SUBSTITUTION: Substitutions should be made a minimum of every four (4) minutes following the rotation system found on page 19. 4. CONTACT Holding, pushing, charging, tripping, or using any part of the body to impede the progress of an opponent is a foul. Coaches should stress the importance of having no contact between players. 5. DOUBLE DRIBBLE: Dribbling a second time after one s first dribble has ended or dribbling the ball with two hands at the same time is called a double dribble. 6. TRAVELING: Traveling (running with the ball) is moving a foot or feet in any direction in excess of prescribed limits while holding the ball. After one stops the dribble, one foot (called the pivot foot) may not move. The other foot may move. When attempting a lay-up shot, one may only take two consecutive steps. Before the third step the ball must be released. 7. BALL POSSESSION: When the offensive team loses possession of the ball by shootingscoring, fouling, or stepping out of bounds, the coaches should instruct their team to run down the court and set up their defense. 8. OUT OF BOUNDS: Any player putting the ball in play after it has gone out of bounds must do so within 5 seconds or lose possession of the ball to the other team. 9. THREE-POINT LINE: No three-point shots are recorded on courts where there is no three-point line. Many side courts have no markings on the floor. All full size courts have a three-point line. 10. DIVISION LINE: Dodd Middle School side courts: once play has passed the back court foul line, that back court foul line becomes the division line or ten second line when moving into the front court. 3

BASIC RULES Boys & Girls: Grades K-3 Introduction & Fundamentals: K-3 will follow all the basic rules as described in Offense, pages 9-10, and Defense, pages 11-15. All players on defense must stay within the box as marked on the floor. Volunteer coaches are asked to teach correct position on all out of bounds throw-ins. Take the time to teach that there is a line on the floor and the feet must be outside the line to make a proper throw in. Teach about fouls, but avoid calling any fouls. Teach about traveling, but avoid calling traveling. Two shot fouls will be shot. No fast breaks are allowed until grade 4. Man-to-man defense may not be introduced in Grades K-1. Man-to-man defense may only be introduced to Grades 2-3 in February and March. There is a game played every meeting. The first 15-20 minutes should be used for drills. The balance of time is used for game time. The supervisor or a designated parent shall call out subs! every 4 minutes. All players have equal playing time. Use the provided basketball rotation schedule to ensure fair rotation. Boys: Grades 4-6 & Girls: Grades 4-6 Skill Development & League Play: Once the teams are formed a team color will be assigned by the Parks and Recreation Department. Follow the rules as listed under Boys Grades 7-8 & Girls Grades 7-9 except as noted. Suggested warm-up procedure: 9:00-9:05 Shoot around 9:05-9:10 Stretch 9:10-9:20 Drills No scorebook is used until Grade 7. Team fouls are not recorded. Personal fouls are not shot. All 2 shot fouls are shot. Limit of 5 personal fouls. Games are straight running time. 9:20-9:39 1 st half 9:40-9:41 Half time break 9:42-9:59 2 nd half Boys: Grades 7-8 & Girls: Grades 7-9 Skill Development & League Play: Once the teams are form a team color will be assigned. Teams can choose a team name if they wish The league will follow all Federation Rules (High School) except where noted. Games will be 4 quarters long. There will be 10 minutes running time for each quarter. During the game the clock will stop only for time outs. During the last two minutes of the 4 th quarter, the clock will stop for all violations as well as out of bounds. 4

The league shall follow the published rotation system for substitutes every 5 minutes of each half and any over times. In the last 2 minutes only free substitution is allowed at the coach s discretion. Only during the last quarter is pressing permitted. Teams that are winning by more than 6 points should not press. Five minutes, maximum, are allowed for the half time. One timeout is allowed per half and one time out in overtime. No time outs can be carried over from one half to the next or into overtime. Each timeout will be one minute. In case of a tie at the end of the game there will be a two minutes overtime starting with a jump ball. The game clock will stop for time outs and all shooting fouls. In the event of a tie at the end of the first overtime a second overtime will be started with a jump ball and the first team to score a point wins the game. Teams can use any type of defense (man-to-man, zone, etc.) George Welch High School Basketball League, 9-12: The league will follow all Federation Rules (High School) except where noted. Games will be 2 halves long. There will be 20 minutes running time for each half. During the game the clock will stop for time outs and all shooting fouls. During the last minute of each half, the clock will also stop for all violations as well as out of bounds. The clock will not stop for all violations in the last half if a team is behind by 12 points or more. The team that is ahead may not freeze the ball. Only during the last ten minutes of the game is pressing permitted. Teams that are winning by more than 6 points should not press. The league shall follow the published rotation system for substitutes every 5 minutes of each half and any over times. In the last 2 minutes only free substitution is allowed at the coach s discretion. One minute is allowed for time outs. Five minutes are allowed for the half time. One time out is allowed per half and one time out in overtime. No time outs can be carried over from one half to the next or into overtime. A player is out of the game when he has committed his 5 th foul. If a player earns one technical, that player must sit out until the next dead ball. If a player earns two technicals, that player must leave the game. If a coach earns one technical, that coach must sit for the remainder of the game. If that coach earns a second technical, that coach must leave the game and will not be permitted to coach the next game. Overtime will be 2 minutes long. The game clock will stop for time outs and all shooting fouls. The team that is ahead may not freeze the ball. 5

DRILLS PASSING: Use the full length of the court, two lines facing each other. Begin with lines approximately 10 feet apart, and then back up as needed. One line has all the balls. Practice using: Two hand chest pass Two hand bounce pass One hand bounce pass One hand baseball pass DRIBBLING: Use the full length of the court, two lines at one end of the court, paired off with partners. Spread the lines the width of the court. One line dribbles the length of the court, turns around and dribbles back stopping approximately 10 feet in front of his partner, passing the ball to him. The partners switch positions and when the coach whistles the next round, the partner proceeds to start his drill. Stress at all times the importance of moving only as fast as one can and still control the ball. Practice using: Dribble with right hand, walking Dribble with left hand, walking Dribble with right hand, jogging Dribble with left hand, jogging Dribble with right hand, running Dribble with left hand, running Dribble with cross-over dribble, right hand to left hand, back and forth, walking Dribble with cross-over dribble, right hand to left hand, back and forth, jogging Dribble with cross-over dribble, right hand to left hand, back and forth, running STOP AND GO DRIBBLING: Set up as in dribbling drill. The coach will use his whistle to stop and start movement. The dribbler begins bouncing the ball in place. When the whistle blows he dribbles until the whistle blows again. The dribbler stops and bounces the ball in place until the whistle blows again. This should be done 3-4 times depending on the size of court and the age of group. Practice using: Dribble, walking Dribble, jogging Dribble, running Repeat above, but backwards 6

SHUFFLE DRIBBLE: (Grades 4-8 only) Set up as in dribble drill. Turn sideways straddling the baseline. The object is to shuffle the feet and dribble the length of the court, turn around and come back, stop approximately 10 feet away and make a good pass to partner. Do not cross over feet, only shuffle. Stress the importance of keeping speed movements under control. Use whistle to include stop and start movement. Practice using: Dribble with right hand, jogging Dribble with left hand, jogging Dribble with right hand, running Dribble with left hand, running BALL HANDLING: Set up as in dribble drill. Move rotation of ball around back going in one direction and then the other. Practice using: Dribble walking Dribble jogging Dribble running Repeat above, but backwards Dribble in a figure 8 moving ball over one leg through the legs to behind the other leg and back to the front without dropping the ball. SHOOTING: Shooting requires confidence and concentration. Practice on game condition shots that you will be able to get and should take when the situation arises. Find the form that best suits you and work to develop it. Know the range and ability of your shots. Practice emphasizing the following: Quickness Keep the ball close to the body Follow through with hand with each shot ending with a fishhook motion with the wrist Keep eye on target front or back of rim, or backboard Keep shot light with backspin Keep control of ball with fingertips Keep body in balance with shoulders properly squared away REBOUNDING DRILLS: Practice emphasizing the following: Get the proper position Timing of jump Quickness of jump Keep hands up Make extra effort 7

DEFENSIVE MOVEMENTS: This is the primary drill for combining defensive stance with the movement of the ball. Each four-man squad is divided into two groups on the baseline, and then that is broken into pairs. One from each pair is the dribbler (shown as 1 & 2), and the other is the defensive player (shown as A & B). The dribbler dribbles the length of the court in a zigzag motion using one half of the width of the court. The defensive player assumes the basic defensive stance and moves with the dribbler down the court. 1 A 1 2 B Practice using the following points of emphasis: The defensive man should always be close to the dribbler but far enough away to allow the defense to go around the dribbler. The defensive man should always have his head directly between the ball and the basket. Emphasis on the ball will ensure that the defensive man will always be in position to pressure the ball with both hands. The defensive player s hands must apply constant pressure to the ball. Playing with palms up, pressure the ball with hand nearest the direction of the offensive player (i.e. if the offensive man goes to the right, use the right hand. The other hand is used to pick up the cross-over dribble.) Players should not cross their feet when moving or changing direction. Suggestion: During the first week of practice, the defensive player should keep his hands behind his back to concentrate on foot movement and keeping his eyes on the ball. The second week, the hands should be used but the defensive player should not try to steal the ball. From the third week on, the defensive player should go after the ball. GORILLA DRILL: Assume the basic defensive stance. Practice as follows: Front 2 step slide forward immediately recovering to original position. Back 2 step slide backward immediately recovering to set position. Slide right or left boxer s shuffle with hands remaining in set position. Sprint right or left cross-over and sprint to cover man returning to a set position on command. Flash proper hand movement in upward flashing of hands. Constant movement feet moving at all times. Raid sprint running in place sit when you can run no more. 8

OFFENSE PARKS & RECREATION PHILOSOPHY: An offensive system is based on the principle of position and movement. The objective is to teach floor position and to develop the knowledge of ball movement through passing rotation of the ball to all various positions, stressing continuous ball movement. This keeps all participants involved in the game. Grades K-3: All offenses will be comprised of the following positions: two guards, one center and two forwards. Skill development with this age group should motivate ball rotation and movement to all various floor positions. Please note that for the safety of all participants at these age levels, fast breaks are not allowed. (See page 4, item ). Grades 4-8: Offense will be developed with daily practice. PASSING: A pass is movement of the ball caused by a player who throws, bats or rolls the ball to another player. Examples are: Two hand chest pass Two hand bounce pass One hand bounce pass One hand baseball pass DRIBBLING: The dribble is used to advance the ball down court, to initiate play patterns, to make drives to the basket, and to move into good shooting position when pass receivers are closely guarded. Types of Dribbling: Player Control Dribble: Used when defensive players are near and the ball must be protected. The knees should be bent so that the body will be low and the ball is dribbled lower and closer to the body. Reverse Dribble: Used to change direction when a defensive player is guarding the dribbler tightly and overplaying in the direction the player is dribbling. (This requires the body to turn and is slower than the switch dribble.) Techniques of the Dribble: It is important to learn to dribble without looking at the ball or either hand. Fingers should be comfortably spread in order to achieve maximum control of the dribble. Dribble with the fingertips and not the palm of the hand. CAUSES OF FUMBLING: Receiver takes his eyes off the ball coming to him. Receiver is not being alert and not expecting the ball. Receiver is mentally or physically tired. Receiver tries to shoot, pass, dribble, or turn before he has possession of the ball. Receiver misjudges the pass. Receiver does not have his hands up and ready. 9

SHOOTING: The Lay-up Shot is a shot taken close to the basket at the end of a drive or after receiving a pass from a teammate. The right foot should be in contact with the floor for a right-hand lay-up, the left foot for a left-hand lay-up. Carry the ball with both hands to a position outside the right hip and step onto the left foot for a right-hand lay-up. Outside the left hip and step onto the right foot for a lefthand lay-up. The ball should be above the head and pushed towards the basket. The Jump Shot is taken as the shooter jumps into the air from in close or as far away as 25 feet away from the basket. Prior to jumping into the air for the shot, hold the ball in both hands with shoulders square to the goal and knees slightly bent. The jump into the air is made with an upward thrust of both legs. The height of the jump will vary with the individual but, as a rule, it should be smooth and effortless. During the jump, the ball is brought to a position slightly above and in front of the head. The shooting hand is used to control the shot and is placed at the back of the ball with the back of the hand facing the shooter. The other hand is used for control. The shooting elbow should be under the ball and on a line between the shooter and the basket. Sight the goal just under the ball and shoot over the front rim. An upward movement of the shooting elbow and a simultaneous forward push of the forearm and wrist releases the shot. The wrist should snap completely forward to provide a good follow through. The shot should be released at the top of the jump. The jump shot should be practiced from three situations: 1. From a stationary position 2. After a dribble 3. After cutting to receive a pass 4. Balance and the upward jump are more difficult in the latter two situations but are of no less importance. REBOUNDING: Rebounding is an attempt by any player to secure possession of the ball following a try or tap for goal. The team that controls the boards usually controls the game. Assume that every shot will be missed, either offensively or defensively, and move into position to rebound and go up after the ball. Whenever a shot is taken, hands should be quickly brought to shoulder height with the palms toward the ball. Take one or two steps backward after a shot and watch the opponent that you are guarding. If the opponent makes a move, cross in front of him and go for the ball. If he hesitates, forget him and go for the ball. Defensive rebounding: Jump quickly and high, spreading legs with a wide kick on the way up, catching the ball with both hands and bring forcibly back to the chest. Take a good look for potential receivers and get the ball out as quickly as possible. Offensive rebounding: Jump quickly and high, keeping fingers spread with palms forward and tip the ball rather than bat at it. Keep the hand up to avoid possible pushing. 10

DEFENSE PARKS & RECREATION PHILOSOPHY: A defensive system is based on the principle of reducing the frequency of high percentage shots, diminishing the chance of a second shot, eliminating give away baskets through traveling, fast breaks and turnovers, and discouraging the opponents from penetrating the defensive perimeter. This takes desire, determination and dedication. Defense: Zone Defense: Grades K-3: All defenses will be a zone 2-1-2 or 2-3. Grades K-1: Defense must keep both feet in the 3 second, paint or key area. Grades 2-3: Zone defense is preferred. Man-to-man defense may be used after February 14 th, not before. Grades 4-6: Zone defense is preferred. Individual defense man-to-man may be used at the start of the season. Grades 7-8 Boys and 7-9 Girls: Man-to-man or zone defense is used. NOTE: Individual defense man-to-man means guarding your opponent only. Team defense man-to-man means that there is opponent switching and development of team play. Grades K-3: All defenses will be a zone 2-1-2 or 2-3. Players should keep hands up at all times and maintain playing in their position. Leaving a position may allow the offense an easy shot from that area. Stress team defense, observing ball rotation procedure, forcing long shots, and preventing easy inside shots. All defensive players should try to get the rebound after the shot is taken. 1 2 1 2 3 4 5 4 3 5 Defense: 2-1-2 2-3 1 and 2 = Guards 1 and 2 = Guards 3 = Center 4 = Center 4 and 5 = Forwards 3 and 5 = Forwards 11

BASIC INDIVIDUAL DEFENSE: DEFENSIVE STANCE: Stay between your man and the basket. Play the overplay position (ball, you, man). Stay between your opponent and the ball when the ball is far away. If your opponent is dribbling, force him to use his weak hand and when he crosses the ball from his weak hand to his strength, make an attempt to get the ball. Drive your man to his weak side, but don t let him drive the base line. Boxer Stance The feet should be slightly wider than the shoulders with the heel of the inside foot in front of the toes of the outside foot. This allows for a quick drop step to the inside. Drop stepping to the outside gives the driver an advantage. The center of gravity should be kept low. The body is bent at the knees, not at the waist, forming a 45-degree angle with the floor. Eye Contact Concentrate on the belt area but look at the whole opponent. Keep head up. Hand Position The forearms should be parallel to the floor with the elbows above the knees. The hands should be spread outside of the knees with the palms up. GUARDING THE DRIBBLER: Assume the defensive stance. Protect the baseline force dribbler to the middle. Overplay to strength stay slightly ahead. Keep palms up to eliminate changeover snap up at the ball. Approach with caution. If your man passes the ball retreat quickly. Guard with your feet do no rush in. Always be an attacker, not a reactor. The reactor is one step behind. Swing step only when offensive strength area changes. If dribbler passes you, sprint to a legal position. Play dribbler tight to prevent the quick jump shot. Always play the dribbler with the inside hand. Take a stand do no permit the dribbler to work you within his shooting range. Defensive Fake drop step, repeat and lunge with inside hand, moving palm across in upwards direction. Defensive Flick Overplay dribbler forcing him to spin, flick ball as he gives you his back. 12

GUARDING THE CUTTER: Drop off one full step when your man passes the ball. This permits room to maneuver and decreases screening possibilities. Do not permit a cutter to move in a straight line. Beat the cutter as he moves to the basket, never trail. Overplay your position by keeping your hand extended in front of the player and your inside foot forward. Keep the ball-you-man position. Follow a player who drops in by facing the ball and feeling for him. Force your man out of his shooting range, so if he does receive the ball, he will be out of range. Driving to the basket or give and go are the only alternatives permitting retreat by one attack step. GUARDING THE CUTTER MOVING AWAY FROM THE BALL: Weak side cutters are moving away from the ball to screen, clear the area, or to come back on a dead sprint on the give and go. Assume the ball-you-man position. FOUR WAYS TO BEAT A SCREEN: Over the top (Best Move). Force your man to go outside and stay in front of the screen. Fight through the screen. Switch. This is called by the back defensive man whose offensive man is setting the screen. Worst Move. Go behind your teammate and the man setting the screen. DEFENDING AGAINST THE JUMP SHOT: Thrust hand nearest the ball upward in an attempt to block shooter as he moves into shooting position. Hang with jumper to force shot and destroy timing. Pressure shooter to change his arc. If shooter has to dribble, move in tight and go straight up with him. Force shooter to receive ball out of his shooting range. Vary your defense one hand up, both hands up, duck under, or walk away shooters are accustomed to firing against one hand up. Force the shooter to think about something other than putting the ball in the basket and the shooter s shooting percentage will drop. GUARDING THE POST-MAN: High Post the proper guarding position is behind the post, sliding behind the post as the ball is rotated maintaining the proper defensive stance. Medium Post the ball is played from the side with near arm extended as in the overplay position. Bouncing overplay. Slide over-the-top to keep ball in sight and prevent a pass as the ball is rotated. Low Post Front the post-man using hands to feel out his basic position and moves. Beat the cut on all moves toward the ball and the basket. The number of attempts by the pivot man to handle the ball must be reduced. The pivot man must be forced out of his favorite scoring spot. Defensive players must sag into area when the ball is moving into the pivot area. Everything must be done to prevent the ball from reaching the post-man. 13

ZONE DEFENSE: Reasons for using Zone Defense: Easier and less taxing to play than man-to-man. Player can play a zone without understanding man-to-man. Zone defense is good for young inexperienced teams who have not yet learned man-toman, slow teams, or teams that rebound well. A good ball player who is in foul trouble can be protected from further trouble by putting him in an area where he is less apt to foul. A good place to put him is on the wing of a zone. Types of zones: 2-1-2, 1-3-1, 3-2, 2-3, 1-2-2, 2-2-1, box and 1, diamond and 1, triangle and 2, and match-up zone which includes more man-to-man responsibilities. The match up zone forms a 2-1-2 zone and changes to a 1-3-1 as dictated by the offense. MAN-TO-MAN DEFENSE: Man-to-Man defense is used for the following reasons: To stop a team that has great outside shooters. To change the flow of the game. See additional reasons under Advantages of Man-to-Man below. Five Ways to Play Man-to-Man: Normal Tight Loose Aggressive or double teaming Switching General Rules of Man-to-Man: You may drop back from your man 4-6 feet if the pass moves away from your man. If a defensive man makes an angle between his man, the ball and you as the defender, watch both the man and the ball, but if in doubt, watch the man. Keep your hands up and beat your man to his spot. Use elbows and body, not hands. Good defense against team with only 2 good ball handlers. Advantages of Man-to-Man: It fixes responsibility, issuing a challenge to each player. It enables individual match-ups of opponents based on size, strength, speed and height. It can force the opposition when they are stalling or when you are behind. It permits effective double-teaming. It affords excellent rebound position, since in most cases the defensive player is inside his offensive opponent. It permits better preparation of each individual, since the coach can tell the player the strong points and weak points of the opponent he is to guard. It provides good use of the fundamentals, providing they have been taught properly. 14

It places high premium on good conditioning. It allows for good fast break opportunities in pressure man-to-man. It is adaptable to any opponent s offense, especially a delayed or wide-spread offensive system. It can be used full court to increase the game tempo. It can be used in all situations during a game or during a season, changing only the team attitude (i.e. tight, loose, half-court, full-court, etc.). It makes it possible to recognize a good individual s defensive play so that the coach can credit the player publicly for his efforts. Disadvantages of Man-to-Man: It is much tougher on the individual physically, requiring excellent stamina and top condition. A mismatch in size during switching maneuvers or an inability to match the opponents may individually hurt the team. It is ineffective against a good screening and cutting team. It requires excellent fundamentals ability and mental attitude on the part of each player. Players are more prone to fouls using this defense. It allows the opponents to exploit the ineffective defensive man by isolating him. It requires flexibility in men who must switch during screening tactics. In addition to their individual responsibilities, players must be aware of team responsibilities. It requires extremely good knowledge of defensive fundamentals. A normal or loose man-to-man defense may not be a good fast break defense. 15
