Great drill to stop the ball, make a steal, force a turnover.
1 starts on the foul line. 2 is on the left side at half court and 3 is opposite to 2. 4 is in the center of the court. 5 is on the other foul line. Once the ball is thrown in, 1 plays defense on the ball. When the player starts to move to a side and is nearing half court, 2 or 3 depending which side of the court the ball is on will step up and try and trap the ball. If the ball is on the 2's side then 3 will move closer to the ball and watch for a pass back or to the center. 4 will shuffle back a bit but stay in the middle waiting to steal any incoming passes to the center or cross court. 5 is still on foul line but if any players are down past the foul line, 5 will move back with them but staying centered. 1 and either 2 or 3 are trying to stop the dribble. Once ball is stopped try to steal it but watch for fouls. Usually someone will come back to help out but have 2 or 3 that isn't on the ball. Hopefully the press works and you get the steal or turnover or they take too long to get it up the court and it will be your possession. If press is broken go back to your regular defense (zone, man to man etc..)
You can switch up the players possitions ex. if your 1 isn't a good defensive player then you can put a better qualified player as 1.
