He's right though. ESPN has their own agenda. You know damn well Dilfer created the QBR to help his pocket passing buddies and discredit QBs like Ben.
Steve Young is so delusional when it comes to Ben it's scary. All because Ben beat his boy Holmgren in the Super Bowl.
As a statistical correlation to QB performance and winning, it is the most accurate predictor of wins (the team with the better QBR in a H2H matchup has won 86 percent of the time over the last 5 years)
Your pocket passer comment is odd, since QBR punishes pocket passers by making Run EPA a part of overall QBR (and rewards mobile QBs). It's clear you don't know anything about QBR.
