OSU has the stronger wins, but that Iowa loss is really not excusable Bama played what looked to be a tough schedule but the SEC turned out to be much worst all around and FSU suffered a pretty mighty collapse down which left them with a much reduced SOS they easily take the spot over the Buckeyes in nearly every other year, I think it is better to beat several really good teams and have a bad loss than to beat pretty much no real notable teams and have the better record so I think Ohio State will be the 4th one in, Bama has the better chance to get past Clemson IMO though.
