Man out of bounds play that starts in a Triangle set, hence the name, and has a screen the screener action for a big.
My team runs this play as well and we find that the player who sets the screen on the screener is almost always open
if they roll back toward the ball and not allow the back board to get in the way of the pass. Take a look at the animation
I don’t believe it has the 4 rolling back but you can figure it out.
