This is an outright lie.
In general, MSU fans don't put any distinction whatsoever between JSU, Alcorn and Valley. If they went to the Alcorn game, they will go to the Valley game.
If there are people calling and asking why play Valley, those same people called and asked why play JSU and Alcorn. They aren't singling Valley out. The JSU and Alcorn games were played and both were well-attended.
The Valley game would have been just as well-attended if for no other reason than it would be the first game of the season and they wanted to see how their team looked.
