Percy - what about a potential metric that ranks a QB based on their team's defensive efficiency.
Essentially showing what QBs have it easier than others.
If a QB knows he has a defense giving up 13 points a game (like Seattle), he can take more risks, take chances deep, and operate knowing that he will be bailed out.
Romo knows that he almost has to play a perfect game, no turnovers, no short-fields for the opposing offense. Because there is little to no chance our defense can stop anyone.
Hell, the Saints didn't even have to punt against us last year - 107 first downs. That's insane.
