BTW, they just replayed that play on Sportscenter and I watched it frame by frame, because of where the penetration came from, there was no secondary help man, when Curtis helped out, he wasn't late BTW, if anything he was early, his man cut to the basket behind him. WILL should have rotated over to Curtis' man. He screwed up twice.
i've got no replay, so i've got no choice but to concede the point.
damn that sucks.
So I just watched it again and I have a different take, although Jake's man was one pass away he should have been the secondary help on Casto on the Moore penetration. When Moore started his move to the basket Jake was guarding Thompson under the basket, with his back to the ball. When Moore got in the lane Thompson moved to the right block (Jake still not seeing ball), and Casto crashed from the left elbow, behind Kelly who turned his back. Jake never saw Moore, Will helped late to Casto. Seeing the play you would think that Jake helping on Casto crashing wouldn't have done any good since he was so deep, but Casto is awful around the rim so it may have made a difference.
If Jake rotated, Will would have needed to rotate to Thompson. So Will was not late on helping Kelly on Casto. None of this changes that he gave up the initial penetration.
