OSU played half the games everyone else did, notre dame got blown out by Clemson. Cincinnati and A&M should have been in over those teams.
But brand name and money speak loudly.
While anything can happen, there are only 2 elite teams, Alabama and to a slightly lesser extent, Clemson. It wouldn't matter who got put in at 3, and especially at 4. Notre Dame, Cincy, Oklahoma, or A&M (who I think deserved it, but were already blown out by Bama once), they were all going to get drilled.
