A lot of this.
Schools at UND's level aren't going to have "revenue" to share. So that is a moot talking point.
At this point, it doesn't sound like any of the Dakotas are looking at opting in at this point, at least in year 1. Probably the smart decision because the rules on what the settlement looks like (aka - what you are choosing to opt in to) won't be known until mid-April. Not sure the thought process for the other FCS schools. But again, one year isn't going to set anyone too far back, especially when no one knows what they are opting in to.
UND would also have to trim some other sports rosters and I'm not sure how that would trickle down and have any possible effects on Title IX compliance.
