Week 6 QBR Leaders

Total QBR is a quarterback rating that takes into account all of a quarterback's contributions (passing, rushing, sacks, fumbles, penalties) to his team's scoring and winning and summarizes them into one number on a 0-100 scale, on which 50 is average.

For a game, the number can be interpreted as a percentile, so a score of 80 means a quarterback's performance is in the 80th percentile of all quarterbacks' games. For more about the methodology and statistics behind Total QBR, see here.

It was a week of extremes as six QBs who played in at least four games this year set season highs in QBR in Week 6 while five set season lows. Rookie starters Andy Dalton, Cam Newton and Blaine Gabbert all set career highs.

Matt Ryan and Aaron Rodgers led the way, as both directed their teams to convincing wins.

Rex Grossman had his worst game of the season -- and the worst overall QBR in Week 6 -- and was eventually benched.

Below is the full breakdown of Total QBR and its component statistics for the NFL QBs with a minimum of 10 action plays in Week 6 through games of Monday Oct. 17.
