The secondary is NOT NEARLY as complex as the corner offense itself obviously. But it merely uses one look I like out of it which is the point guard in the corner on the ball side, ball is on the wing. The wing enters the ball to the high post and screens down for the point and basketball plays ensue. Below is the basic corner offense, the first clip is the action I like. In the first clip, the Wolves actually do run it as a secondary. The other difference is that while Coach Adelman does it with two posts, the version I would run has four perimeter players.
Once teams start to cheat it, the point guard can then curl the screen to the basket for a layup. If that isn't there, the wing who screened (2) pops up to the high post, takes the handoff, and attacks the rim with the same idea. On the drive, the point fills the backside corner.
