Nice job. While I loved the players that have graduated and moved on, it was the 111th ranked offense, so maybe it's not so hard to replace as we may think. I think we win anywhere from 5 to 7 games.
I did account for the offensive ranking last year in my prediction. A low-ranked offense one year is a positive indicator for the upcoming season, meaning that I increased ISU's expected power rating as a result of having low yardage output in 2010.
