Which is a problem. You have to be wary of who is IN the game, not who is out...
I mentioned in the beginning of the game that the Rockets came out like the Magic did in that series clincher against the Sixers. When Howard/Yao are in the game for their respective teams, they are the focal point of the offense and it's more of a half court oriented offense. When they're out, you check out who is remaining in the roster and gauge how the team is going to run their game plan. The Magic have a set of perimeter players around Howard, and the same goes for the Rockets and Yao.
As far as the Hawks, they had no shot of beating the Cavs with or without Johnson, Williams, and Horford at full strength. The difference is that Cleveland don't give a fuck who's in front of them, they'll still do what they do...
