How AFC South QBs measure up

Let’s have a look at how the quarterbacks of the AFC South are faring in passer rating and QBR, shall we?

Passer rating maxes out at 158.3; QBR goes to 100. Here’s ESPN.com's QBR file.

For a game, QBR can be interpreted as a percentile, so a score of 80 means a QB’s performance was better than 80 percent of all QB games.

A reminder on Total QBR: It’s a quarterback rating that takes into account all of a QB’s significant contributions (passing, rushing, sacks, fumbles, penalties) to his team’s scoring and winning and summarizes them into one number on a 0-100 scale, where 50 is average. Since 2008, the team with the higher QBR has won 86 percent of the time.

Blaine Gabbert’s strong showing before he got hurt on Sunday in Oakland produced great ratings.

His passer rating for the season went up from 73.3 to 77.1, a pretty good increase based on an incomplete game.

Only Aaron Rodgers and Drew Brees topped Gabbert in QBR on Sunday.

I am a fan of QBR -- and any statistic that gives us an increased measure of performance. But here's a recent story from Aaron Gordon at The Classical saying the stat hasn't had the impact its creators expected.
