Alot of great QB's have a mixed history in the playoffs. Peyton Manning for all of his greatness has a 9-8 playoff record. As of right now he's no better than Favre. 1 Super Bowl win with an average performance. Dan Marino wasn't so hot in the postseason with a career postseason passer rating of 77.
I wouldn't say he's overrated. He's a top 10 QB comparable to Dan Marino.
