W ith just one week left in the college football regular season, the only thing we really know about the playoff field is that we don't know anything for sure about anything yet.

Boise State is on pace to beat the Big 12 champion for a first-round bye in the College Football Playoff, and with Tulane on the rise, could the Green Wave push the conference entirely out of the 12-team playoff?

Because of the way the College Football Playoff bracket is constructed, Indiana is the last team in the 12-team field. Two teams ranked lower than Indiana would make the field as projected conference champions.
