It would certainly impact the pipeline, as a WAER Sports and Newhouse alum I can say that I might not have chosen SU if it was not in a major conference. That had a lot to do with my decision - you want to be covering big games. Now, once someone picks SU, that has nothing to do with it. We had the worst four year run of sports in school history while I was there and we have some successful alums already.
As far as our powerful alums getting involved - there's not much they can do other than donate money and tell Gross to do his best to get us in a good situation in the end, but I'm sure he's trying to do that anyway.
