Looking at the SWAC schedule for 2017...so I guess Grambling and MVSU are going to play each other this season, but it's going to be a non-conference game. They must have had trouble finding a non-league opponent on short notice.

It reminds me a little bit of North Carolina and Wake Forest, which are going to play non-conference games against each other in 2019 and 2021 (though that is happening for a different reason).
