The correlation between passer rating differential and win percentage in the league since 2004 (the year the rules changed to favor the passing game) is a staggering 0.92, which means that 85% of the variation in win percentage in the NFL is accounted for by quarterback play, your own and the opposing team's.
Now, the only way one gets around that finding is by arguing that passer rating isn't a measure of quarterback play.
If so, then we have to abandon the idea that Ryan Tannehill has played better individually, as measured by his passer ratings, when his offensive line has been healthy.
Are you trying to argue that Peyton Manning in 2013 wasn't better than Peyton Manning in 2015? Or that Kurt Warner wasn't better than Dilfer? Or that Rodgers and Brees aren't better than Flacco?
Because if that is not what you are saying, then you are avoiding the question......
