Word is that Oden's knees are healthier than Bynum. Bynum has a degenerative knee problem, it won't ever be great. Oden had microfractures in one and an overuse injury on the other from coming back too early. He took so much time off to fully heal up. Remember how injury prone Grant Hill was until he stopped trying to come back too soon? Microfracture surgery has advanced and he took his time. If he.could pull a Grant Hill style return at a younger age he may still make it.
