Our weekly look at quarterback play

The AFC South got reasonably good quarterback play in Week 13 in two wins and two losses.

T.J. Yates was composed in his first start and Matt Hasselbeck sufficiently supplemented a big day running the ball with Chris Johnson in wins. Dan Orlovsky put up big numbers closing the gap after the Patriots bolted to a big lead. And Blaine Gabbert had the first two-touchdown game of his career in a Monday night loss to the Chargers.

Here’s a breakdown of AFC South quarterbacking Sunday, with QBR (and rank for the day) as well as passer rating.

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.
