This drill is designed to teach the denying of a guard to forward pass and when the ball is passed guard to guard, the drill teaches players to fall in the lane while playing weakside defense.
Two players need to occupy guard positions on opposite sides of the top of the key. One guard has a ball. On the same side as ball, are an offensive and defensive forward with the defense, while one pass away, denies the pass as the offense v-cuts trying to get open. After a few v-cuts, the ball is passed guard to guard. The defensive forward falls to the ball on the pass, still denying while having his hand in the passing lane. Offensive forward waits a count of one second before moving, either with a high post flash or running the baseline to occupy the forward spot on ball side. I teach opening to the ball, closing, and then once again denying the pass while the offensive forward v-cuts. If the offense makes a high post flash, I teach taking him on, physically stopping the flash with a raised forearm, then forcing the offense out on the floor while denying the guard to forward pass.
I have found that making the offensive forward wait the count of one second, while not necessarily game like, helps to teach the drill. Make players go full speed and be physical. I also at times do not allow a back door pass to be made which ensures that the defensive player will get out and deny the perimeter pass.
Coaches can take the spots of the guards. This allows the coach to determine what passes are made and when they are made. Another variation is to have offensive and defensive forwards on both sides of the court at the same time. This allows for weakside help. Then add defensive guards which allows for rotation when weakside help is warranted.
Pressure passing lanes both one or two passes away
