You know what, I did the research, because I'll put this on the show. By my count there are 26 non P5 schools that have a non-conference opening. Of those 26, 9 aren't already playing 2 or more non-conference road games or are independents looking for more games. Here's the list.
Florida International
Florida Atlantic
UTEP
Army
Massachusetts
Buffalo
Central Michigan
Ohio
Arkansas St.
Florida International already has two games against P5 opponents, they would seem unlikely to add a third. Arkansas State is already at Auburn, they would seem unlikely to add another SEC road game. Central Michigan already canceled a series with us recently, it seems unlikely we'd go back to them. UMass has 5 road games, they have played 6 every year so far in FBS, but they are already at Florida. They might be open to it, but I don't think they would schedule another SEC road game. So you are left with these 5.
Florida Atlantic - Only one road game so far, against Kansas State.
UTEP- Only one road game, against Texas.
Army - Has 3 slots open on its schedule, has 3 road games, has played 5 road games the past few years.
Buffalo - Only one game on the OOC for them, at Nevada.
Ohio - Only two games scheduled, one on the road at Kansas.
So if my research is right, these are our five options.
Now here's the real rub. Let's use UTEP as an example first. UTEP averaged 34200 fans a game last year, at an average ticket cost of $28. So just ticket revenue alone for a home game for them will be over $900000. That's before anything else is sold, and obviously they don't have the costs of transporting the team and so on. My guess is your million dollar price tag is way low for what it would take to get a team in here at this juncture. We might be 1.5 million, maybe more.
