There's always a ton of discussion on this board about passing offense, with people dismissing our passing offense because of the lack of total yards or touchdowns. Statistically, total yards and touchdowns are a pretty bad indicator of success.
Chase Stuart did this study in 2012: http://www.footballperspective.com/correlating-passing-stats-with-wins/
ANY/A, NY/A, Passer Rating, and Touchdowns per Attempt are the stats most correlated with winning.
Since this is a Bills forum, and Tyrod is obviously going to come up, here's where he ranked the past two seasons:
2016
ANY/A - 18th
NY/A - 24th
Passer Rating - 18th
TD % - 18th
2015
ANY/A - 9th
NY/A - 11th
Passer Rating - 8th
TD % - 13th
By these measures, Tyrod was around QB #10 in 2015, and QB #20 in 2016.
