This is an injury that could have just as easily happened warming up before the game, during practice, during workout, on a walk to the 7/11, or crossing the floor from the living room to the kitchen. Not trying to make any judgement here, or second-guess Doc's decision to play Shaq, but whether or not Shaq warmed up then cooled down, or whether or not he should've played more or less than five minute stretches, or even whether or not he played at all, has very little-to-no bearing on this type of injury.
