I had wondered about that. Plus...seeing him play the other night I noticed he would have to lose some LBs to make height/weight!He can't join the Army Reserves because of his contract. Surprised he didn't know about that before going public with it, but good for him nonetheless.

Got in touch with him and told him not to waste his time.
