It’s idiotic for a FCS school to make a rushed decision on joining FBS, let alone the worst conference in FBS. Corona brought up Texas St and UTSA joining the WAC 10 years ago, just to jump to FBS. I am not going to dissect the timeline and all that, but that was 10 years ago. What was the end result? Worked out fine for UTSA and Texas St. Not so much for Idaho and NMSU.
On top of that, you’re taking your olympic sports out of regional conferences to fly them to El Paso, Miami, Nashville, and wherever else. North Dakota St probably buses to all their basketball games in the Summit League, except for maybe Denver and Oral Roberts. That costs more money, on top of more football scholarships and added women’s sports.
Joining CUSA is all risk, with little reward.
