The purpose of the 2 on 1 denial drill is to teach how to deny the ball. By using two players, emphasis is also placed on double-teaming. This drill is also good for offensive players in that it allows them to work on receiving the ball when being double teamed. This would be especially good for a post player. This drill also forces the players on the perimeter to work on their passing.
Place players around the three point line with only one basketball. Select three players to go inside the three point line. Two of these players will be assigned to deny the other player the ball.
The players on the outside are trying to get the ball to the player that is being guarded. If they cannot get the ball to that player, they throw the ball to another teammate, who is also behind the three point line. The defensive players need to try to get three steals. Once this happens, another one of the three becomes the offensive player. This continues until everyone involved has been on both offense and defense.
