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 season, a Total QBR of 65 or better is roughly Pro Bowl level, and a rating of 75-plus is MVP level. For more about the methodology and statistics behind Total QBR, see here.
Tony Romo, Tom Brady and Drew Brees all had stellar weeks, but were unable to gain much ground on Aaron Rodgers in Week 10. Rodgers had another strong game on Monday night, posting an 84.8 Total QBR. He has been the best QB in the league by a fairly wide margin.
Despite a win against the Colts in Week 10, Blaine Gabbert remains the worst of the 34 QBs who qualify this season.
Below is the full breakdown of Total QBR and its component statistics for the 34 NFL QBs on pace for 250 action plays this season.
