PD, what the hell are you talking about? The main reason why Oden was drafted #1 is because his athleticism is off the charts. Physically, he's superior to Durant in every way. Leaping, running, benching,etc, you name it.
Randolph is one of the least athletic big men. You're the first person that's ever called him explosive. Weber was a good athlete but still not quite as good as Oden.
Oden would definitely have to adjust his game if he lost some of his athletic ability. Most great athletes have to adjust their games when they lose some of their physical abilities. I think Oden will make a close to 100% recovery though because of his age and the medical knowledge today.
