He's had a few injuries and missed most (if not all) of 2012 IIRC due to injuries to his back/legs.  I don't know the details of his injuries but back injuries (especially for a big man) are rough ones to deal with.  I had a back injury in my early years of high school (almost 10 years ago now) and it still plagues me from time to time.  He's young and probably has future health in strong consideration here.   I can't blame him for that one bit.

 

If he's saved his money even remotely well he should have enough to retire on too.  I hope for his sake he has and he finds success in whatever he chooses to do outside of football.
