Two players and one screen. The screener steps into the ball handler’s defender, the handler uses the contact to turn the corner, and the screener rolls to the basket. Two offensive players have now occupied three or four defenders, and one of them is behind the play.
Why coaches use it
It is the cheapest advantage in the half court. You need two players who can execute it and three who know where to stand, which is why the same action works at U14 and in the NBA. Very little else scales like that.
It also produces a decision you can scout. Every team guards the ball screen a particular way, and every way of guarding it concedes something specific. Find the concession, drill the counter, and you walk in with an answer already prepared.
The two roles are not interchangeable. The screener decides the angle and whether he is rolling, popping or slipping. The handler decides whether to use the screen at all. Teach both jobs on their own before you run it live.
How it is guarded
- Drop. The big retreats toward the rim and the guard chases over the top. Concedes the pull-up.
- Over or under. Nobody switches. Over takes the three away and gives up the drive; under does the reverse.
- Hedge or hard hedge. The big steps out to slow the ball for a beat, then recovers. Concedes the roll and the short roll.
- ICE. On a side screen the guard refuses the screen and pushes the ball down the sideline.
- Switch. Simple, and it leaves a mismatch somewhere on the floor.
- Blitz. Both defenders trap the ball. Three defenders now have to cover four.
Draw the action once, then replay it against each coverage in turn and watch which of your reads still holds up. The simulated defense is in beta and shows you positioning, not outcomes.
