AFC South weekly quarterback comparison

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.

Jacksonville’s Blaine Gabbert suffered in QBR because of a late fumble of a shotgun snap for which center Brad Meester actually took all the blame.

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.
