He's probably getting some weird shit done to it in the locker room during those little time outs. Sports medicine is crazy as hell nowadays.
Wade definitely looked bad for stretches in game 4 though, so I don't think the Heat can afford many more injuries against the Pacers. The big three were all kind of bad actually, and the three point shooting is still not there. It's kind of funny considering the talk about how crucial three pointers are to 'modern' NBA offense that the Knicks and Golden State are out of the playoffs, and the favourited teams in each of the conference finals have shot a pretty poor 3 point % in their series' so far (or are the Grizzlies/Pacers). Entirely meaningless, but funny.
