How Come everybody thinks Tom Brady is the best because of his rings?????

Terry Bradshaw won 4 super bowls in 6 years. About the same as Brady. BUT, in all these discussions I don't hear his name come up as the best quarterback in history. Peyton Manning will break most of Dan Marino's ercords, if not all. Dan Marino NEVER won a super bowl. And he's considered as the best. So, stop with the Tom Brady propaganda, please!
