I’d put the four you mentioned ahead of him, plus Bart Starr, Sid Luckman, Sammy
Baugh, and probably Matt Stafford too. I’d put him more on par with Russell Wilson, Philip Rivers, and Eli Manning, and even then, only because of his Super Bowl rings. I think all those guys are better QBs than he was. Probably Lamar Jackson and maybe even Jared Goff will also end up being higher than him on the list of best QBs ever, among others.
