Yeah it will be wild to see what this does to the NCAA basketball tournament too. Do you give a 20-team Big 10 four auto-bids, or do they just get 14 teams into thing regardless? But other than that issue, the basketball conferences that don't have D1 football shouldn't be affected too much.
Unless, of course, this kills the NCAA as an entity and the conferences start running basketball too.
Yeah I suppose it's possible that once the existing FBS schools sort through the wreckage they will try and get FCS schools to come on, rather than vice-versa. I mean, Temple would be just fine as an FCS school, and Nova would be irrelevant as an FBS school.
