JR, WSSU joining the MEAC is a totally different thing than SU not giving the SWAC office a date to schedule around. When new teams are added to the conference, OOC games have to go. You are seeing that a lot with the FBS schools when they add teams. The first thing they do is cancel series. Thta is apples and oranges from what you are talking about. That's like when the SWAC went from 7 games to 9, we had to cancel our series that we had planned with NW State.
I bet the SWAC office KNEW to hold Labor Day weekend for Houston-SU and they know when to hold games like JSU-TNState and they know when to schedule the MCC, etc.. I don't think SU submitted the date and they tried to fix what they messed up on the back end. Broussard may not be a dummy but he messed that one up. Just like you said, he has your games set for the next several years.. i bet he has already submitted those dates to the SWAC office.
