Here’s a breakdown of AFC South quarterbacking Sunday, with QBR (and rank for the day) as well as passer rating.


Passer rating maxes out at 158.3; QBR goes to 100. Here’s QBR for everyone this week.

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.

Gabbert was about 16 percent above average in both categories.

Some details on Gabbert’s QBR from Albert Larcada of ESPN Stats & Information:

His lost a fumble hurt his QBR but isn’t factored into passer rating, but he made up for it with his clutch play on that last drive -- including the 2-point conversion, also something QBR takes into account that passer rating does not.

Overall these positives and negatives essentially cancelled each other out in QBR, making his QBR nearly identical to the less sophisticated passer rating.
