Line the team into 2 single file lines 10 meters apart facing the same direction; front player in one line runs forward with the ball roughly 3 - 5 meters, then passes to the front man of the other line; they run forward 10 paces and turn; the original passer runs the dummy diagonal hard line; ball carrier doesn't hit the runner but turns back and passes back to the first player of his line; new ball carrier passes to the first player of the original line and the drill goes on as before.
Simple and easy to run in small space at a tournament as a warm-up!
Step 1: Form two lines roughly 10 meters apart in 'Indian file' as below. First player runs forward with the ball and passes to the first player in the other line. The player who has passed the pall then runs across in a support line.
Step 2. Supporting runner offers themselves as a short option. Player with the ball passes back to next player in their line, who has started to come up to take the pass. This player then passes across to the first player in the next line, who runs forward. The player who has passed the ball then runs a supporting line offering themself as a short option. The player with the ball then passes to the next player in their line who passes back across to the other line and the process is repeated.
