Matt Schaub only played 10 games this season but had enough touches to qualify for the Positive Impact Factor (what's this?) standings and he led the AFC South this season. Instead of his usual nemesis Peyton Manning, Schaub was in a battle with Matt Hasselbeck for the top spot.
Here's the 2011 AFC South PIF Standings (PIF with sacks counted as rushes like the NCAA in brackets):
1. Matt Schaub, Houston Texans, 38.4 (47.1)
2. Matt Hasselbeck, Tennessee Titans, 38 (44.2)
3. Blaine Gabbert, Jacksonville Jaguars, 15.2 (28.9)
4. Curtis Painter, Indianapolis Colts, 0 (19.9)
Schaub recovered from a down year in 2010 (23.3 PIF) with a 38.4 this season (his second best season). He was able to improve by increasing his touchdown production rate while slashing his fumbles lost. He did not quite get back to his 2009 season, a 46.1 PIF, which was second the NFL behind Peyton Manning.
Hasselbeck rebounded from his worst regular season (-5.2 in 2010) to his third best career mark this season with a 38 PIF. Last season he turned the ball over 22 times while scoring only 15 touchdowns. In 2011, he had 18 touchdowns to 15 turnovers but only lost 1 fumble.
Gabbert did not have a great year for a rookie. He produced 12 touchdowns at one of the lowest rates in the AFC at 2.6% of his touches. He also turned the ball over 16 times. His interception rate was actually pretty good which should give Jacksonville fans some hope that he continue to develop and can improve his ball security (14 fumbles this year).
Curtis Painter was thrown into a bad spot this year for the Colts and had a 0 PIF. He produced only six touchdowns at a rate of 2.3% of his touches (last in the AFC). His rating was severely harmed by his lost fumbles. He had 12 total turnovers on the season.
