• Variation #2 (10-15 min):  "Double Line."  Same as the above variation except there are two lines in opposite corners of the box to start.  Players move in the same direction and try to avoid getting overtaken by the other line (Variation #2A).  Whichever line gets overtaken or gives up the largest lead, has to do extra sprints at the end of the drill.

• Players can also perform this drill while cradling a ball (Variation 2B); if a player drops a ball, the whole line has to stop and wait for that player while they go get the loose ball.

Variation #3 (10-15 min):  "Loose Balls."  Same as the above variations except the player who runs to the front of the line rolls a loose ball out into the middle and the player at the back of the line must retrieve the ball and repeat the action (Variation #3A). 

The other option is for the player who retrieves the loose ball to pass to the player at the front of the line, who then rolls it out to the next person at the back of the line (Variation #3B).
