Talking about leakers forcing Kanter to rotate to them. If Favors and Kanter were out there together, Favors would stem the leak because he's quicker. , then logical rotations would ensue until opposing offense is forced to reset.
You're absolutely right that we have no control over what an opposing guard does after burning our perimeter defense. If they go Kanter's way (kanter in paint, not rotating to foul line/elbow) he goes straight up in the paint, which is what he's been doing. That's about the best you can ask of any non shot blocker when the guard is coming at you.
