In 2016, Browns rookie quarterback Cody Kessler had an uneven year. He went 0-8, but he ranked 24th in ANY/A out of the 31 quarterbacks who started at least 8 games and threw at least 150 passes. His stats weren’t great, but they weren’t 0-8 bad, either. In PFR’s Adjusted Net Yards per Attempt Index, which attempts to adjust for era, Kessler ranked 15th out of the 43 rookie passers to meet the 8 start/150 attempt threshold. It was a pretty good rookie season that came with an 0-8 record.
And then there was Brock Osweiler. The Texans quarterback — now on the Browns — was dead last with a pitiful 4.34 ANY/A average last season. But for the second year in a row, Osweiler produced a winning record despite poor play; Houston went 8-6 with Osweiler under center.
I calculated the winning percentage and Relative ANY/A (i.e., ANY/A adjusted for era) for each passer since 1970 to meet the 8 start/150 attempt threshold. I then calculated the standard deviations above/below average each passer was in each category. Here are the results for 2016, and here’s how to read the Kessler line: he started 8 games for the Browns and had a 0.000 winning percentage. His Relative ANY/A was -0.34, so just a hair below league average. He was 2.53 standard deviations below average in winning percentage, but only 0.28 standard deviations below average in RANY/A. As a result, he was 2.24 standard deviations better in RANY/A than he was in winning percentage; that was the highest number on the list. Passers at the top had much better stats than wins; passers at the bottom (highlighted by Osweiler) had better wins than stats. [click to continue…]
