Army and Navy are in the AAC. Liberty and New Mexico State landed in Conference USA. UMass decided to head back to the MAC. Sacramento State's efforts to become an FBS independent aren't working out. In a year, Oregon State and Washington State will be members of a fully stocked Pac-12 again. (They aren't really indies now, either, but I'm putting them in here because I didn't want to write a two-team conference preview.)
The indie party has thinned out significantly in recent years. It looks like we'll be down to Notre Dame and UConn by next year, and, one of these years maybe those perpetual "UConn to the Big 12?
