Schepp 3 on 3 ballscreens
They play a lot of 3 on 3 (and some 4 on 4) where they work on decisions and put players in other spaces.
Make reads based on how the defence defends the ballscreens.
See Shooting - Schepp ballscreens, Tactics - Schepp ballscreens, Attack/defend - Mike MacKay ballscreens, Defending - Messina ballscreens.
a) Offside wing
2 is on the offside wing, 3 passes to 1 from the weakside low post and follows to ballscreen.
If 1 turns the corner, 2 slides down to keep the triangle (if he stays it's a straight line as 3 rolls).
Against a hedge, 1 opens up and drags it, 2 lifts looking to make a triangle pass to 3, 1 can kick it to 2 or attack the hedge again.
b) Ballside wing
2 starts ballside.
If X3 hedges, 2 has a great angle to make a pass to 3 on the roll.
If they don't hedge well and 1 comes off hard, 2 fills from behind.
c) Offside block
3 ballscreens, 2 is at the weakside block.
If X2 helps on the roll, 2 can step in and seal him for a pass from 1 (shown).
If X2 doesn't help (stays with 2), 2 lifts to the elbow, looks to get the ball for a triangle pass.
d) Ballside block
2 starts at the ballside block, lifts if his man helps on the roll (yo-yo the backside, shown), otherwise spaces out.
