I am interested to see how the 105 man roster and portal affects FCS. We know some of their best will get FBS offers, like Nebraska has with the Idaho DB, but I imagine the dwindling rosters in FBS will help them too for those in the portal without a chair when the music stops. FCS Final 4 is Montana State, SDSU, USD, and NDSU. That region of the country dominates FCS. Adding in that the Mountain West and Pac-12 refuse to merge I think it's probably a matter of time before one or two of the Big Sky powers dip their toes into FBS for a new challenge.
