Alabama already cancelled their trip to Michigan State in 2016 (and replaced it with a home tilt against Western Kentucky), and it appears they're rattled by the prospect of playing in Cincinnati:
Not sure if this is out there, but Tuberville told me discussed Bama-Cincinnati game for '15 not looking good. Bearcats want home-and-home

Of course, Alabama can make more money off neutral site games than games at Cincinnati, and they do still owe Nick Saban tens of millions of dollars.
Long live the home-and-home series!
