Week 5 QBR Leaders

10/11/2011 - NFL

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.

Alex Smith led the way with a 98.2 Total QBR in Week 5, as the 49ers routed Tampa Bay. Smith's rating was not only the highest of the week but also the highest for any quarterback in any game so far this season (minimum 15 action plays).

Ben Roethlisberger finished second with a Total QBR of 91.4, while Aaron Rodgers and Tom Brady topped the 80 mark again. Kyle Orton finished with the lowest Total QBR of the week before being benched for Tim Tebow, who put up a pretty impressive 83.2 himself.

Below is the full breakdown of Total QBR and its component statistics for all 28 NFL QBs with a minimum of 10 action plays in Week 5.
