1. Tom Brady
When you combine statistical greatness, consistency, clutch performances and winning in the regular season and playoffs, there is simply no better quarterback than Tom Brady. The sheer number of playoff games he's started in equal more than two full regular NFL seasons, making his longevity in the game even more impressive, and his .730 winning percentage in them is also staggering.
He's not thought of as a stat monster like Manning and Brees, but Brady's individual statistics are nothing to overlook, including the fact that he's thrown for at least 3,500 yards in every full season he's played since 2002. He currently sits atop the all-time list for playoff passing yards, at second all-time in interception percentage and fourth all-time in passing yards, passer rating and game-winning drives led.
But the stats that rule them all are his six Super Bowl wins, which is unmatched among all quarterbacks. Quite simply, if you want to put your team in a position to win a title, there's been no one better than Brady.
