Whatever the move is, refs will find a way to stop it. Undercutting a jump shooter is supposed to be a foul - unless your name is James Harden, in which case it's a no-call
I've said it a few times and I'm half joking, but only half: Remember when Harden used to fake a three and run in to take a pull up jumper at the elbow? He's going to bring that action back, but his fake will come from far enough behind the three point line that when he runs in for a pull up jumper its not at the elbow anymore, its right at the three point line.
I think he'll spend his summer working on his right hand, especially passing. If defenses keep shading him hard to the left, he'll have another weapon.
Passing with his right hand better. For fun; I would love to Harden post up near the baseline, and dream shake/ step back to a corner 3
