He's number one statistically in the post season in wins, yards, tds, completions, and has gone to more divisional championship games then any qb ever...
In the Super Bowl he's statistically number one in yards (1277), tds (13), starts (6), and tied at number one for wins (4) and mvps (3)..
He's done it all with constant revolving parts on offense, especially at wr and rb (brown, patten, givens, branch, stalworth, welker, moss, ochocinco, Edelman, lafell, amendola, then at rb Antoine smith, Corey Dillion, law firm, marouney, redman, Ridley, vereen, bolden, Blount, gray, ect). He did it in an era where teams had to structure their teams carefully around a cap space (unlike Montana). He now has the longest gap between Super Bowl wins, just further showcasing how his talent has sustained the ultimate longevity. I mean, at this point, he's gotta be number one. If you still wanna say joe, then it should be 1a and 1b between the 2.
