Under the current CBA, a team will offer Oden 3 yrs, 24 million if not more. He is worth the risk for a lot of teams, because the reward could be tremendous. There is a reason he was picked ahead of Durant even with the injury concerns. Oden, if healthy is a game changing center. He is that good. The odds of him being healthy are of course small, but if he is, he is a World Series game 7 bottom of the 9th, 2 out, grand slam when trailing by 3. He can be that good.
Portland also realizes this, so he won't come cheap in a sign and trade.
