Their future OOC games (according to fbsschedules.com):
2016: Presbyterian, at Oklahoma State, UNLV, at Virginia
2017: Rhode Island, at Kansas, at Syracuse
2018: at Oklahoma State, Kansas, at Michigan State
2019: at Wisconsin, Washington State
2020: at Northwestern, at Nebraska
2021: at Washington State
Looks like two straight-up home-and-homes (Kansas, Wash St), two one-for-twos -- OKSt (CMU's home game was this year) and Syracuse (it was at CMU last year), and the rest are money games (not sure whether MSU in '18 was part of a home-and-home since MSU played there in '12). CMU may be competitive vs most of the "P"5 opponents.
