It wasn't that he just cramped up out of the blue, he took a knee from Midtgaard to that thigh a couple plays previous (remember the first time he was writhing on the ground in pain but eventually popped up and made both free throws?), then soon after he made that drive, tried to elevate with that same leg and, as anyone who's played sports would know, had that leg seize up on account of the previous muscle hit. Had nothing to do with hydration. I guarantee there'll be talk of a thigh contusion for him tomorrow or whenever.
