The Eagles are the only team in that list that really matters when discussing today's pass happy NFL and they got there on the arm of a very good and potentially elite QB in Wentz. As for the Broncos, Manning's passing skill was diminished, but he's still one of the smartest QBs to play the game, dropping him from elite to very good (continuing the semantics discussion). Eli and Simms were both good, not great QBs and certainly not mediocre QBs.
I agree, but considering we are talking Franchise QBs, good still does not equate franchise QB.
