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.
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.
