Using the NEPA logic, we can calculate the point impact of every turnover this season. Briefly, we look at the points we can expect a team and their opponent to score based on their down, distance, spot and time remaining before the play to that after the play. -TO is the total point impact of turnovers for each team this season and -TO/TO is the average point impact per turnover.
It should be no surprise that Kansas State is on top. Alabama is 5th, but McCarron and crew would like the -8.8 against Texas A&M back (and -6.3 against Georgia almost cost them as well). That Louisville and West Virginia score so high is a real testament to Geno Smith and Teddy Bridgewater.
At the other end, Hawaii, Western Michigan, Tulane and Idaho have cost themselves more than 100 points. Idaho averaged a remarkable -10 per game this season; seeing as how they were outscored by 27 points per game this season, though, those 10 points probably would not have saved their season.
