Nebraska as a win for Taysom Hill and it is not included as a game started and won for Tanner Mangum. Mangum played a substantial part of the game and a meaningful analysis would include that as every bit as valuable a performance as a "started" win against a P5.
2. It's a little bit of chicken/egg in that you have to take into consideration the relative strengths of teammates, opponents and coaching with those other statistics.
Taysom Hill had the best record of the bunch. And his freakish running ability led to a lot of those wins.
Take home message: Taysom Hill was awesome. And his running ability led to great wins. IMO, you can't get much comparative value from the remainder of the information.
