Statistically speaking, Favre holds all major records, won 3 MVPs and a Super Bowl. He's the best ever.
Brady, Manning, Unitas, Montana, Aikman, and Elway are all in the pack too.
According to statistics, it was Sammy Baugh.
The rest is a matter of opinion, and is all biased
Payton Manning or Terry Bradshaw. They hold some of the most records, and some of the best passer ratings.
Statistically, Brett Farve
I would say Joe Montana
Tom Brady easily.
Brett Favre is THE toughest quarterback ever. He is also the BEST quarterback ever.
not the best but he is dam good and he won 3 mvp awards.
John elway the best of all time
Joe Monthanna
I believe that he is the best of all time just based on his stats he's closing in on almost all of the passing records and he's currently the best QB in the NFL and he's 37 and that's pretty old for an NFL player.
Archie Manning
jamarcuss russel by far
Brett Favre
