I'd show FSU and Clemson how football in the ACC will keep them out most years. That should help them come.
FSU is very lucky computers are no longer 1/3 of the formula. Lots of computer models where they aren't in the top 4. Ohio State and Michigan State should feel very lucky too. Computer polls rarely have either of them in an 8 team playoff scenario, let alone a 4 team playoff. There's really very little argument for a Big Ten team in a four team playoff this year. If FSU were some other ACC program and not an unbeaten name school defending champ you'd hear people talking about leaving them out too.
