Yesterday, I looked at the 34 quarterbacks to throw 1,000 passes from 2011 to 2017. In that group, there were four quarterbacks who stood out with low interception rates and high sack rates. All four are black, which is pretty unlikely to happen by random chance given that there were just six black quarterbacks in the study.
But that was a small sample. Today, we expand the group to look at all quarterbacks with at least 1,000 career pass attempts who were active in 2002 or later. For each quarterback, I looked at their INT% and sack% in each season, and measured those rates relative to league average. I have plotted the career grades on the graph below.
On the X-Axis is interception rate relative to league average; it spans from -1.5% (which means 1.5% worse than league average: i.e., really bad) to +1.5% (really good). Tom Brady and Aaron Rodgers are the two at just over +1.0%, while Tommy Maddox is at the far left at -1.26% (he has the worst era-adjusted interception rate since the merger). On the Y-Axis is sack rate relative to league average: at the very bottom, of course, is David Carr, at -4.7%; at the very top are Peyton Manning (+3.3%) and … old Bears QB Jim Miller (+3.0%). [1]Miller played from ’95 to ’02, so he just makes it into the study. To be clear, if a player was active in ’02, his entire career was included, which is just another reason why we … Continue reading
So for purposes of this chart, you want to be up and to the right, which indicates better than average sack rates and better than average interception rates. There are 22 black quarterbacks who threw 1,000 passes. I have plotted them in red, while all other data points are in blue. Take a look: [continue reading…]
