QBR Season Leaders: Week 9

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.

With another spectacular game (94.5 Total QBR on Sunday in San Diego), Aaron Rodgers increased his Total QBR for the season to a ridiculous 88.0, more than 13 points higher than any other qualifying QB this season. Drew Brees made the big move at the top of the rankings, passing Tom Brady for second after Brady struggled against the Giants and Brees played well in a victory over Tampa Bay.

Tim Tebow's 36.0 Total QBR against Oakland wasn't great, but it was enough to take him out of last place in the rankings.

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.
