Mahomes benefitted being drafted by a 12-4 team, sit behind Alex Smith as he lead them to another AFC West title at 9-6 under Smith and 1-O under Patrick. He likely doesn't get those chances here. Mahomes a great player no doubt but also ended up in a great situation in KC. I doubt he does the same in Chicago (see they don't draft Mitch) or here.
Gailey had a pretty good offense lead by a 7th Round QB, 7th WR and undrafted RB. Gotta wonder what if had he kept Lynch and we draft Dez Bryant instead of Spiller how good we'd be.
