Unlike Bowie, I think Oden was the right pick at the time based on what was knowable then. If one could go back in time and make the pick a-new, of course you select Durant.
Bowie was the wrong pick to make, but not due to the results. If you take Michael Jordan and he suffers a career-ending injury in his first season, that wouldn't have made it the wrong pick. Bowie was the wrong choice because he wasn't the most talented player left on the board. Even at the time, people knew Jordan was more talented. It was out-dated "wisdom" like "you take big over small" and selecting need over talent that led to Bowie's pick.
On the other hand, Oden was viewed as the best player in the draft. Not by a lot, but everything I read suggested that scouts considered Oden as much of a slam-dunk first selection as they'd ever seen. And I still think they were correct in their talent appraisal...injuries derailed his career, not a lack of talent.
