What Oden does best is what a dominant big man is supposed to do: rebounds, blocks shots, intimidates...just generally changes the tone of the game. Even though he is clearly not yet adjusted to the NBA, when he's in the game..you KNOW he's in the game. His presence is felt. His offensive game will come. Will it ever develop into dominance on the offensive end? Not sure. However, I do know if healthy (and I would put the risk of injury for Hawes and Oden about equal) he will ALWAYS be a beast defensively.
This is not a knock against Hawes who has greatly impressed me, but just trying to be objective.
