I'm going to start getting pretty worried about Oden if I dont' see some major improvement from him this year, especially in (as everyone has already mentioned) the foul department and his back-to-the-basket game.
I've always felt that you can tell which guys are going to be really, really good by the end of their second year in the NBA. Guys that can *really* play are usually making "the leap" by then. I've tried to think of examples of guys who struggled mightily for the first few years of their career only to wind up being true stars, and I could only think of one: Chauncey Billups. I can't think of one elite big man who was not at least a little dominant by the end of their second year. Duncan, Ewing, Hakeem, Shaq, Yao, Howard, Dirk, Garnett, Malone, Amare, etc.... ALL those guys were well on their way to super stardom at an early point in their careers. Conversely, the guys who are mediocre at best (think Dampier or Ostertag) all kinda struggled from day one and never stopped.
I know there are injury issues in Oden's case, but for that "historical precedent" reason alone, I'm going to be worried if Oden doesn't take major strides this year. And I think the team may have to decide if they still want to sink major, major dollars into the development of the player.
