Indianapolis’ Curtis Painter had the best quarterbacking day among AFC South signal-callers on Sunday.
All four teams lost, but by both QBR and the traditional passer rating, Painter outdistanced the competition by a good margin.
Tennessee’s Matt Hasselbeck and Houston’s Matt Schaub had the same game according to passer rating. But QBR, which includes more factors and hit Schaub hard for his game-ending, end-zone interception, says the two performances were actually 18.4 points apart.
Comparing QBR with passer rating for AFC South quarterbacks from Sunday:
Passer rating maxes out at 158.3; QBR goes to 100.
For a game, QBR can be interpreted as a percentile, so a score of 80 means a QB’s performance was better than 80 percent of all QB games.
Here’s a rundown of the whole league.
