The thing that worries me is Rodgers concussions, at least with Flynn on board, if AR goes down, we don't immediately suffer horrifically at the most important position on the field. If we do trade him though, I am not sure I want draft picks for him, I would rather a veteran (not old) OL or DE to just play his position well enough to allow our already young and established play makers to do what they do best.
I have always hated the idea of moving up spots by trading established players. You get rid of someone you know lots about and have invested time and money on developing, for what could be luck of the draw, you could get a Clay, or you could get a JaMarcus Russel...
