Two things about that post....and while I am at it welcome to the newby whoever you are.....wherever you are...:)
Two things which make me feel a bit better about the Luck situation in general
The Bo Jackson blood flow retirement thing (well that was a long time ago), I would like to think medicine has progressed in dealing with this just like how medicine has progressed with ACL repair/recovery.
The second point, I was encouraged by seeing Andrew Luck at the end of the season, he was looking more like his old self musculature wise in his upper body, I would think blood flow would preclude or at the very least making building muscle mass difficult if not impossible.
It might be a bit true that maybe that WAS an issue and why he took a trip across the pond to "overcome" that impediment in Europe.
