I don't know why people think I'm so biased despite being a patriots fan -- I'm not out there lobbying aggressively for Brady.

Peyton will absolutely be the best statistical quarterback in history, no question about that. Maybe even considered the best "master of the game" and I'm certain he will be a great coach one day while Brady will probably fade away comparatively. But will Peyton be the best quarterback of his generation? That's really the question you need to think about when asking that question. It's pretty much at the point that the "generation" (let's say since 2000ish) is set and it's gotta be between:
- Brady
- Manning
- Brees
- Rothelsberger
- Rodgers

When you think about those quarterbacks careers, who is the best quarterback of that generation?
