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.

Despite being idle, Aaron Rodgers saw his season-long lead in Total QBR increase after second-place Tom Brady had an average game against the Steelers in Week 8. Michael Vick passes Tony Romo for sixth after defeating him head-to-head Sunday night in Philadelphia.

For the first time this season, Tim Tebow qualifies for the season-long ratings. Unfortunately for him, he enters at the bottom with a Total QBR of 12.8 for the season after a paltry 3.4 on Sunday against the Lions.

Below is the full breakdown of Total QBR and its component statistics for the 35 NFL QBs on pace for 250 action plays this season.
