Michigan State vs 1-3-1
See YouTube video - Attacking a 1-3-1 zone
Michigan State attacked an extended 1-3-1 zone defence using an "offset" 2-1-2 with two wide guards, a high post, shooter on either wing, and low post opposite.
Look to get the ball to 4, who is active in the middle of the zone, and can attack and/or pass to 5 or 3.
The guards are also active, and look to penetrate on a guard-to-guard skip pass before the defence can recover.
(Option - use a double high-post entry, see below and Zone offence - X-gap vs 1-3-1
The guards usually reverse the ball at least once (skip pass).
3 can cut to the basket on the pass to 4.
4 can step out to reverse the ball.
Here 3 and 5 swapped sides of the floor.
5 can move out from the low post when the ball is on his side, here 4 steps out top for a pass and hits 5 on a high-low.
Hubie Brown - X zone attack vs 1-3-1
The guard without the ball should never be ahead of the guard with the ball, trail so he can reverse the ball if they trap.
3 and 5 stack to start, 5 breaks up to the elbow with 4 at the other elbow.
On a pass to 5, 4 dives to the front of the rim and 3 busts to the corner. If 5 passes to 3, 5 busts to the first hash.
Here 1 passes to 4, who looks for 3, 2, or 5 (diving diagonally).
If a high-post pass is not there and the ball is reversed, 2 attacks the top of the key with two dribbles and jump stops, 4 drops to the first hash, 5 backs up, 3 goes to the corner, 2 can shoot or has three other options.
