B1G Champ.Been number one in my computer poll all year long basically, better OOC than LSU with each also having a handful of ranked wins in conference. Allowing bias this poll because I think the SEC is way, way more top heavy than the B1G.
1/1 in Tier Aa: The committee got it wrong. Ohio State has been the best team for most of the year according to my computer and nothing they've done on the field has made me feel otherwise, even having a lackluster 1st half against Wisconsin. 
Dominant and just barely shy of the best resume. JK Dobbins, Fields (Heisman finalist), and a potent WR corps create a fearsome offense coupled with Heisman finalist Chase Young on defense should create significant issues for most teams. That being said, I don't see their defense looking as invincible as one (especially Big 10 fans) might expect in these playoffs.
Also a good win, but that first half spent struggling with the Badgers kind of costs them in the long run. Ryan Day should be lucky for that little comeback of his.
