You're again assuming he wasn't going to just get cut after mini-camp.
His initial rookie contract was for $20M. He'd have probably made $50K going through the minicamps and preseason. If the writing was on the wall, hes giving up very little by retiring.
My wife has Crohns, McClainb was simply a name I remember from the year he was drafted (high first, and I told my wife as much when he was drafted) affiliated with the disease. Matt light also fights it. Something tells me this ***** partied it up and ate "well" (steaks, fatty laiden high end restaurant food, booze) and this certainly would play a role in retirement.
Believe me, i'm as disgusted as the next person affected by the disease. I wish he turned out to be a success story to the likes of Matt light. Obviously not the case.
