Tony Romo won the Positive Impact Factor (what's this?) for the NFC East this season. However, it's Eli Manning, who finished third during the regular season, who is in the playoffs. Here's the 2011 NFC East Positive Impact Factor Standings (PIF with sacks counted as rushes like the NCAA in brackets): 1. Tony Romo, Dallas Cowboys, 42.8 (50.5) 2. Michael Vick, Philadelphia Eagles, 36.1 (40.2) 3. Eli Manning, New York Giants, 25.4 (37.2) 4. Rex Grossman, Washington Redskins, -14.4 (15.5) For Romo to win the regular season PIF is a little surprising. During his career, he has usually posted a decent number during the regular season but nothing like this year. In fact, his 2011 PIF was the best of his career. What changed this past season? He produced touchdowns at a higher rate and didn't lose fumbles at his average rate. Michael Vick was second in the NFL behind Tom Brady last season with a 52.7 PIF, the best of his career. This past season was a return to normalcy for Vick. His touchdown rate went down while his interception rate went back up as did his rate of lost fumbles. Eli Manning had a bit of a bounce back year from the 10.1 PIF he put up last season (28th in the NFL). His career low came in 2009 with a dead-last -48.2 PIF. His best season came in 2008, a 29.4. While his fumbles lost rate is still troublesome, his touchdown rate came up and interception rate went down. Grossman has never finished with a PIF number in the positive side in his NFL career as a starter. This past season was his worst season. His best season was a -4.4 in 2006. Grossman can produce touchdowns at a decent rate but his turnovers come way too often be it interceptions or fumbles lost.
