With his overall command of the system, I don't think there has ever been a more cerebral QB than Peyton Manning...and his stats aren't too shabby either. On pure accomplishments, you simply cannot argue against Tom Brady either (system QB or not). There is literally zero argument against those two being #1 and #2 all time. So...you have EVERYONE else to choose from to round out your top 5, and I'm sorry...Rogers is not going to be in that group. He might be one day, but not right now. That would be like Cam Newton having another MVP-type season next year, and them vaulting him into this conversation based on how he is revolutionizing that position...you just cannot do this mid-career.
