At lest with a playoff its not arbitrary. Top two teams in a conference go to the playoffs. Simple as that
None of this crap where an undefeated team (weak schedule or not) does not even have a shot at the championship.
Also, there are some inherent difficulties in determining who the top two teams in each conference may be. Who are the top two teams in the SEC this year? LSU is certainly one of them, but who is the other -- Tennessee (who won their division but lost in the conference championship game), or Georgia (ranked #5 in the nation)?
