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.

Total QBR

ESPN introduces Total QBR:

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.

Matt Hasselbeck had an extremely efficient game Sunday, leading the way with a Total QBR of 97.8 on just 21 action plays. Aaron Rodgers was just behind him with a Total QBR of 96.2 on a whopping 52 action plays. On the other end of the spectrum, Mark Sanchez had one of the worst games of the year, committing four turnovers and putting up an abysmal Total QBR of 0.6.

Below is the full breakdown of Total QBR and its component statistics for all 32 NFL QBs with a minimum of 10 action plays in Week 4.
