I didn't understand much of what was in the posts of that thread but I think the following:
1. The 'big' programs are not all going to stop scheduling the 'cupcakes' and have their huge stadiums sitting empty in the early season while they're on the road playing at their 'big' brethren for half the $$. Even if Tosu tries to do this, which of the bigs are going to forgo a home sellout to go share the pot w/Tosu? Is Tosu really going to give up revenue that supports their massive athletic program and provide fewer games in Cols. for their passionate 'fans'? I'll believe it when I see it.
2. I don't see us playing in Div. 2 at Infocision and I don't see any other MAC teams doing it either, so why would BG? At worst, BCS seems to be sustainable by a lot of largish mid-major schools, even without a 'big' money game (YSU only went to Pitt this year). I honestly think that poster is confusing Div. 2 with '1-AA' (which also has a non-scholarship option).
3. If BCS would choose to separate itself completely, Div. 1 non-BCS would become a new NCAA division and there would be no need for anyone to go anywhere else.
