The 9th (or 13th or 17th depending on the preferred format) has a much much weaker case though than the 3rd.

Right now, a team can do literally EVERYTHING right, and still be on the outside looking in. It happened to Auburn in '04, it happened to Boise last year, and there's a decent chance that it could happen to South Florida this year.

Tell that to Auburn & Boise State.
