Points For and Against Faucette: Points For = 14; Points Against = 10
Box Score Team: Earned dpoints = 69; Gift Points = 51 (38) Opponent s Block v. Hitting ball out of bounds (36 errors; 13 on blocks)
Box Score Statistical checks if keeping both sides 1. Service Aces = Reception Errors 2. Kills + Aces + Block Solos + ½ Block Assists + Selected Opponents Errors [(AE TTB) + SE + BHE] = number of points your team scored in a game (match).
Total Match Florida = 88 Earned Kills = 57 SA = 1 Team Blocks = 11 TOTAL = 69 Gifts Received Texas AE(20)-TB(11) = 9 SE = 9 BHE = 1 TOTAL = 19 69 earned + 19 Gifts = 88

Rotation Analysis Six Possibilities Name derived from Position of Setter in system The rotation(s) in which your team scores the greatest number of points are your strongest. This may vary by match but teams have patterns that develop over a season. For best success play as much of a match as possible in your strongest rotations and as little in your weakest rotations

Examples of Strategic Situations for using Rotation Analysis Q. If my weakest rotation by a lot is Rotation II where both my O1 and M1 are in the back row, what rotation should I start in? O2 Opp M1 S O1 A. III M1 O2 Opp S O1 Rotation II Start in RIII, 5 rotations from your weakest one
Examples of Strategic Situations for using Rotation Analysis We cannot get out of Rotation IV unless we pass perfectly because my O2 can t score against a double block and set defense, what should I do? Have your M1 hit from the left side on S M1 O2 the first ball and let your O2 hit a 2 ball in the middle or from the right side O1 Opp Set your Opposite or O1 in the back row Start in Rotation V and pray for an Rotation IV opponent serving error when you get tt to Rotation IV only half kidding
Am I playing someone with a predictable starting rotation? 9 11 1 Who Blocks and Digs Ronda Rocket? CnI Can get tmy weaker krhittr Hitter away from Betty Block? Am I in my best reception formation when Jenny Jump is serving? Matchup Worksheet
