Funny you mention that. I was thinking the same. I hope it doesn't happen but he himself has been talking up defying the aging curves. There has been all this talk about him being in great shape and stretching (as if somehow this concept is an epiphany not duplicated by other pro ballplayers and provides a Kevlar vest against age/injury).
He missed big parts of 2 seasons in his 5 year deal and last year his shoulder.
I'm sure its beneficial, but there is only so much one can when you are 36 playing O and D in a long, grinding season.
