Penn St isn't going to leave and walk away from that money. Plus they have a 100,000+ seat stadium to fill, they aren't going to want to stop playing Ohio St, Michigan, USC to schedule 6 or 7 home games vs the Eastern Michigan's and Toledo's of the world where their best home game is vs Boston College or Syracuse.
If you think SU splitting away from the ACC or whatever is left of it, and Syracuse fans are going to fill the Dome to watch SU vs Akron I don't think that is a rational take. Speaking for myself, I would never go to the games and I wouldn't even watch SU on TV at that point. And yes, I would be home watching Big 10 and SEC games.
I think there are a few safe assumptions that fans are missing.
1) These schools care far less about wins/losses than fans do, its all about getting that big fat TV money paycheck from the conference. Winning or losing is a small part in the overall big picture of what these schools think about in regards to conference realignment and such.
2) No school is going to openly leave the Big 10 or SEC and those conferences aren't throwing any schools out. Not happening.
3) If you think the SEC/Big10 splitting away will "hurt" TV ratings or viewership and fans will stop watching, that is a bit naive. Fans watch what is plastered in front of their faces. So if ABC/ESPN, FOX, CBS, and NBC are carrying those schools and games in the prime TV time slots...people will watch. Plus those games will get all of the coverage and hype Monday thru Friday in the lead up to each Saturday.
I understand where college sports, specifically college football is going. I don't like it. I know Syracuse will probably be left behind at some point in the near future and that isn't good for us Syracuse fans. But let's have some perspective here.
