I think the committee is sinister enough to move ND to #4 (because they have no "13th data point") and to move either OSU or Oka (should they win their conference championships) to #3. I think OSU is will be the eventual #3 team because of their defense vs Michigan keeping Oka at #5.
The committee will do just about anything to give Alabama an easier path to the championship (this all if Bama wins their conference vs Georgia.)
GO IRISH - beat everyone.
