Ohio State moved up four spots to No. 9 in the College Football Playoff rankings after its 45-point rout of Michigan State on Saturday.

The Buckeyes (8-2) were ranked No. 13 before crushing the Spartans 48-3. But the lopsided losses to Oklahoma and particularly to Iowa still weigh heavily to the playoff selection committee.

“The loss to Iowa was a convincing loss in the eyes of the selection committee that Ohio State suffered,” selection committee chair Kirby Hocutt said in a teleconference. “Still, (Ohio State is) an extremely talented and good football team.

“The selection committee was extremely impressed with the win and the manner in which the win came about last week against Michigan State. The win over Michigan State and the win over Penn State are victories the selection committee continues to be impressed with. But again, the losses to Oklahoma and Iowa also weakened their resume at this particular time.”

Among teams with two losses, Ohio State is ranked behind Auburn at No. 6 and Notre Dame at No. 8. But the Buckeyes potentially could pass both of those teams. Auburn must play No. 1 Alabama on Nov. 25. Notre Dame, as an independent, would not have the opportunity to make a closing statement by playing in a conference championship game.

After playing Illinois this week, the Buckeyes play No. 24 Michigan. If Ohio State plays in the Big Ten title game, it would face Wisconsin, which is No. 5.

Hocutt said there were essentially two tiers of teams. He said there wasn’t much of a gap among the top five teams, and the same was true with the cluster of teams behind Auburn.

“When we got into discussion of teams from 7-11, there was not a lot of separation, he said. “There was a lot of conversation about that particular order. (Ohio State was) not far away from being a spot or two higher, or a spot or two lower, either.”

Linebackers update

Ohio State coach Urban Meyer said on the Big Ten coaches teleconference that Jerome Baker has been cleared for Saturday’s game while Dante Booker is questionable.

Both outside linebackers missed the Michigan State game apparently because of concussions. In their absence against the Spartans, Tuf Borland played middle linebacker with Chris Worley moving to the outside spot and Malik Harrison playing the other outside linebacker.

Neither players nor defensive coordinator Greg Schiano would say whether Booker practiced Tuesday.
