Durant is a really special player. But he has to find his way to compete with other PF in the NBA. Or he could thy SF. The best thing is that he will be a all-star if he can play with his own way. BUT if he can't, he will just f*** up his whole career, like the JJ something from Duke.
On the other hand, Oden is the much less risky 1st overall pick becuase his size. But so far it looks like that is pretty much all he has (in the standard of a NBA center) He does not play as smart as Durant. He does not know how to use his energy effectively. Also, he is not tough enough. Just look at when he was 1v1 with Richard. Oden did not give any pressure when he was defending Richard. That is extremely dangerous cuz the main type of pro center he will face are virturlly muscle beasts.
But anyway, he will deserve 10M per year in the pro if he is doing what he is doing right now. He gets paid based on his size, power, and popularity he gained in college.
But if wants be the next A. Sturdmire or the next D. Howard, he has a long way to go.
