You are truly in a bind with this one, but I think Bradford is the better choice out of the given QBs. McNabb is pretty horrid, MIN is going to be after Cutler all day, Gabbert is facing a strong pass D in PIT, and Moore... I don't have anything to say about him, haha.
So, out of the given choices, I think Bradford is the better one. SJax is finally healthy, meaning Bradford will be more comfortable, and who knows, this might be a high scoring game with the potent GB offense.
Good luck man, and thanks for help on mine.
