Growing up in the 80s, I got to see all these guys first hand. As a 49er fan, Montana will always be the greatest to me because he won 4 SBs and maybe would've won more if they didn’t trade him. IMO he could’ve beaten that 92 Cowboys team in the NFC championship game in SF. However, as good as he was and as good as Marino and Elway and even Favre were, I’ve never seen anyone as good as Rodgers.
Arm strength as good as anyone yet with accuracy that’s better than everyone. He won a chip with a 6th seeded team that had no business doing anything. I don’t think people realize just how bad some of those recent packer teams were and he was taking them well into the playoffs and championship games. When Rodgers broke his collarbone a few years ago, that Packers team that was in the NFC Championship game the prior year had to go to OT to beat a Browns team that went 1-31 in those two years. The guy was basically singlehandedly beating everyone except for the very best teams. He might not have the gross stats that Brees has but he’s got the ones that translate to individual contribution, like the all-time leader in passer rating and an incredible 4/1 TD - INT ratio. Plus he can read defenses as well as anyone ever has.
People are losing their minds about Mahomes and he’s awesome but he’s got what are arguably the best players at their positions to help him out. Rodgers was doing everything Mahomes is doing but with inferior talent. If only the Niners had done the right thing and selected Rodgers with the #1 pick instead of Alex Smith.
