The read on the switch depends on personal setting the screen. If you have a big setting the screen and there is a switch, we have the classic small covering big going to the basket, and we want to find him and get him the ball. If there is a mismatch for the ball-handler, and he has the opportunity to turn the corner, then that is a good option.
Let us watch Duane Notice (blue jersey # 10) set a screen for Sean Patrick. Sean (blue jersey # 7) sees the switch and turns the corner to get to the rack.
