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.
Tom Brady of the Patriots and Ryan Fitzpatrick of the Bills remain 1-2, though Fitzpatrick closed the gap thanks to a higher Week 3 score than Brady in Buffalo's 34-31 victory over New England. Fitzpatrick has been remarkably consistent so far, posting three consecutive weeks of 80-plus QBRs. Brady has three consecutive weeks of 70-plus QBRs.
Below is the full breakdown of Total QBR and its component statistics for the 31 NFL QBs with a minimum of 75 action plays through Monday, Sept. 26.
