Squirrel Crossing for large groups to eliminate long lines at the net post waiting to play in. Objective is for all players to focus on point play and move in to open positions quickly.
Divide players into two teams. Uneven is okay. Game is played inside service boxes only. Two players from each team take the court in the service boxes. All others are lined up behind the service line waiting to play in. Coach is at sideline feeding in first ball of each point.
As in Squirrel Crossing, the waiting player takes the place of the player who makes an error. Player making error moves to end of their team's line. This game needs to move quickly - coach can be merciless and is under no obligation to wait until replacement player is ready.
