Many offenses, even if they do not specifically run the Flex offense, they will often utilize the baseline flex cut. This article will help you learn how to defend the flex cut.
When defending the baseline flex cut, it is preferrable to body up and force the cutter low and possibly out of bounds to take him out of the play.
By forcing the cutter low, the player defending the screener can also stay close so he cannot step back into the lane and get a pass after screening.
The main objective is to keep the cutter below you and to not allow him to step in front. Force him to alter his path to the post.
It is also very important that the on-ball perimeter defender pressures the passer. The perimeter guards should not be allowed uncontested post entry passes!
In this diagram, X1 pressures the passer. X2 is in drive-help position and then steps up to pressure O2 when the pass is made. X5 three-quarter fronts O5 in the low poast and X3 is weakside help.
In this diagram of the flex cut, you see X4 bodying up and forcing O4 low. X5 denies in the post and X1 is in position to help on the middle drive. X3 helps X4 on the cutter and then recovers on a pass to O3.
