Matt Schaub of the Texans had the best game of AFC South quarterbacks Sunday when measured by the NFL’s passer rating. But according to the alternate metric, QBR, Indianapolis’ Curtis Painter had a better day.
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. It takes a lot more elements into account.
The Colts allowed the fifth best quarterbacking game of the day by QBR. Cincinnati’s Andy Dalton posted an 88.8 (and a 111.5 passer rating). Baltimore’s Joe Flacco was also good, with a 74.5 QBR (eighth) against the Texans to go with a 78.5 passer rating. Against Jacksonville, Ben Roethlisberger of the Steelers had just a 49.5 QBR but a 96.3 passer rating.
Here’s a rundown of the whole league.
