College Football is back as of today, which is awesome. Yesterday, I used the Positive Impact Factor in a space I hadn't yet published, College Football News, to provide a couple of case studies from 2012 as well as an explanation of the rating system.
I picked Air Force-Hawaii and Kansas-Texas Tech as examples of interesting games where the traditional Passer Rating lets us down. In the case of Air Force QB Connor Dietz, he had a 0 Passer Rating because he didn't attempt a pass. He, along with the rest of the Falcons' rushing attack was highly efficient and his PIF, by contrast, was a 92.9.
In the KU-TT game, Seth Doege was shown to have vastly outplayed KU QB Michael Cummings. The game went to overtime and was decided by a wildcat TD thrown by a Red Raider running back. When the game was on the line, Cummings was the one to extend it to overtime with a huge run (which set up a field goal) and an earlier Doege interception changed the momentum and the early lead Texas Tech had. As a result, the PIF ratings were a more even 66.4 to 60.9 in favor of Doege.
For me, it was a crucial time to give new readers a chance to check out PIF because ESPN is now going to push their win-biased, narrative fitting, have to watch film to subjectively determine Total QBR into the college game as well.
