I think it is a great idea and would be a great move for ASU and FVSU, the only drawback would be the attendance. I know that some of the PWI's on the list dont turn out all that great for games and we would probably suffer at home games.
Attendance really would not be much different than what we see today. Outside of HC, where high attendance numbers are a given, the only other SIAC team that brings numbers to FV is Tuskegee. We do not play Albany ST in the Valley so.....IMO, there would not be any difference.
