You are never getting an elite P5 program to play in Western NY for an OOC game no matter the venue.
could the stadium be better, of course, maybe it is me but I would be just as likely to drive 7 hr to see UB play at the old Rotary field ( it is not there anymore right? But the point is the same) as I would UB stadium or whatever they call the Bills stadium these days. Maybe Vman or rma, who travel to a ton of stadiums are better able to comment but if there is a team you want to see does the venue matter that much? I agree a venue may get you to try a place for teams you do not care about once but again and again?
the issue is not the stadium but the general lack of interest/culture and a stadium is not going to fix that for more that a few games, IMO.
