"Hold on thar, BabaLooey!"
The wing rotation is the key to how the SU defense works. I'll try to be lucid.
Two rules: 1.) with every pass, every player moves; 2.) defend the 3
So: ball comes up the middle of the floor; guards do
not allow entry to high post.
- Ball to wing; G1 pops out to defend ball, G2 fronts high post; W3 defends corner; 5 defends low post/short corner; W4 sags to "the hole"
- The offense will invariably skip-pass to their off ball wing; so W4 (in the hole) must pop back out to that wing, until the G2 gets over, then the wing slides down to defend the corner; G1 comes across to front high post at the new ball side elbow. W3 now sags into "the hole." (mirror image).
- If the ball does make it into the high post, 5 comes to defend, W3 and W4 must collapse to the low blocks.
- The key to making the whole thing work is knowing your job, but also recognizing it early enough to respond.
- There are traps, etc, and a few other wrinkles, but that's the basic idea.
So now, I'm guessing what you're getting at is how some teams, after watching film, will try to screen the weak side wing (in the hole) as they skip/reverse the ball, and at the same time leak a shooter out to the wing. The answer is the winger in the hole must have his "head on a swivel" and not allow himself to get screened inside on the reverse. He can then get to a perimeter shooter while the defense re-positions. It's a tough job, but if you're 6-7 or 6-8 and play at SU, you better be able to do it.
The other thing is that when the O skips the ball over to the opposite wing, G2 is very easily screened because he was fronting the high post. Again it's a tough job to get around it, but if you're 6-3 and play at SU, you better be able to do it. Triche, MCW and AR were particularly good at this, and SU was very successful while they played those spots.
