I agree here. If there's no risk of having the same injury (which seems the case...bone spurs don't pop back in when you land wrong), his injury risk on a given play is the same as anyone's. It was GREAT to see him get up like that after he's blown some dunks this year. Give him confidence that he can do stuff like that.
In a related note, it was nice as well to see him, in the first quarter, put the ball on the floor and blow by Boozer for the foul call. I know it's boozer, but good to see.
Back to injuries, it's pretty random what causes fluke injuries. For instance, I'm much more worried about him going out of his way to still goal tend after whistle shots. It's meaningless, and when you're not trying 100% like you are during a game play, injury chances increase. Remember TA's infamous injury?
