In playoffs, it's all about defense (not QBs)
Much of the focus heading into Sunday’s Conference Championship games will be on the quarterback play, particularly with future Hall of Famers Tom Brady and Peyton Manning facing off for the fourth time in their postseason careers.
But if recent playoff history is any indication, it’s not the quarterbacks who will have the most impact on which teams get a trip to MetLife Stadium, but rather the defenses’ ability to stop those quarterbacks that will make a bigger difference...

A more rigorous analysis using multiple regression shows that the quarterback’s QBR entering the game is still significant in the postseason, but the defense’s QBR allowed becomes more predictive in the postseason. The small sample size of the postseason means that this pattern might be due to random fluctuation, but the trend is still something worth keeping an eye on.
