Greg Oden is easily the worst first round pick ever when looking at his giant red flags and the player taken #2. He looked like he was 40, hobbled around on broken knees like he was 60, couldn't stay healthy for a thirty game college season, and couldn't play above average offense in college. Taking him #1 meant saying no to Kevin Durant. My thoughts were the same on draft day as they are now, I've always been shocked he was even a top five pick, definitely shocked he was taken over Durant.
Sam Bowie who many would bring up was a phenomenal NBA player compared to Oden. Darko has been much better than Oden and Carmelo and even Wade aren't Durant.
