An increase in the number of seeds in the FCS playoffs?

[taper]

Look no further than the recent CFP.
-Undefeated ACC Champion Florida State - out. (corollary - undefeated SoCon champion)
-One loss Big 12 champion Texas - in. (corollary - one loss CAA champion)
-Second team from the SEC Alabama - in. (corollary - 2nd team from Big Sky)

That's a terrible comparison. CFP only has 4 teams which means one of the P5 champions has to be left out. Florida St was consistently the lowest ranked P5. Committee got it right. Alabama was SEC champion, not 2nd team.
