Tim Tebow won the AFC West 2011 Positive Impact Factor (what's this?) standings with plays like the one above. As you might have seen yesterday, he was on fire against the Pittsburgh Steelers in the playoffs. You'll have to wait to see how Tebow ranks in the playoff PIF. Let's just say he's off to a good start.

Here's the 2011 AFC West 2011 Positive Impact Factor Standings (PIF with sacks counted as rushes like the NCAA in brackets):

1. Tim Tebow, Denver Broncos, 37.9 (43.4)

2. Matt Cassel, Kansas City Chiefs, 24.8 (35.2)

3. Carson Palmer, Oakland Raiders, 23.7 (32)

4. Philip Rivers, San Diego Chargers, 5.7 (28)

Tebow did not have enough touches to qualify in 2010 but showed that he could play with quality with a PIF of 55.8 (Tom Brady had the highest PIF last season with a 58.4).

Matt Cassel had a setback from his 2010 season career-best PIF (47.2) which was 7th in the NFL. He was also slightly below the 25.3 he put up in 2009. His turnover frequency stayed relatively low this season but his touchdowns also plummeted.

Palmer was down from a 2010 PIF of 26. He's been trending down since his career-best season in 2005 (45.1 PIF, 4th in NFL). His touchdown production is still good but his interception rate is too high to make it back into the 30s or 40s.

Philip Rivers was down from a 23.4 in 2010 but not as low as his 2.6 in 2007. He's not been able to come close to his career-best 44.2 PIF in 2006 (5th in NFL) since achieving that mark.
