Timing is everything.
This SLOB gets the ball into the 3 of a zipper cut, then turns into middle screen. There is some initial delay on the weak side to create a possible separation for 2. If she doesn't get the ball, then she continues through to screen for 1.
Problems? This doesn't get rebounders near the glass and potentially 5 has to be the primary defender in transition. If you have the right timing and the right personnel, this gets a lot of action going to the basket.
