Brady and Manning are great QB's in the "can't touch the QB" era of the NFL. I agree that Peyton Manning is great, but his brother has a better post-season record. Unitas, Montana, Elway, Aikman, Bradshaw, and Favre to an extent are all great for any era. I can't include Marino in that group for the same reason I don't include Dan Fouts - no Championship wins.
