It's tough for any player at any age to go thru a full season....than take it up a notch or two in the post season.
Tyson, I think can last because he will not be asked to do too much. However, the constant banging down low in the paint will wear you down over time but if he stays in BBall shape he'll out last many centers in the league simply because his contributions will be limited. I wouldn't mind him developing a low post game thou, but I'm not expecting it.
I don't think the olympic games will be that taxing on either of the players, I see it as a workout, staying in shape.
