Coach throws ball to any offensive player. Once the ball is passed the defense must sprint back and match-up as the offense is running down the floor and attacking. **The defensive player across from the player who was initially passed the ball must sprint and touch the baseline first. Creating a 5 vs 4 situation in which your defense must scramble and help each other. On a score or stop, the play goes back the other way 5-on-5 for only 1 possession (Def. becomes Off., Off. becomes Def.)
