If Mahomes wins that 2nd SB and has a period of 7 or 8 years of greatness (wins 2 more League MVP's) than he will be in the discussion with the Peyton's, Brady's, Montana's, etc.. So I agree with your "maybe". Eventhough football is a team game, some don't realize how big it is to win at least 2 SB's as a starter. A QB is just looked at differently when that happens. Bill Russell once said anyone can lead their team to one championship because of circumstance or getting lucky, but when you lead your team to two it is not a fluke. League MVP wise, Mahomes will never catch Peyton, Peyton won 5. Just like I don't seeing anyone ever having more SB wins as a QB than Brady who has 6.
