Ohio State won the Big Ten championship with a 27-21 victory over Wisconsin. On Sunday, the Buckeyes will find out if that was enough to secure them a spot in the College Football Playoffs for the third time in its four years of existence.

Ohio State was ranked eighth this week, though playoff chair Kirby Hocutt said there was little separation between the Buckeyes and No. 5 Alabama. Auburn and Miami, along with Wisconsin, lost their conference championship games.

Alabama (11-1), which lost to Auburn last week, didn’t play in the SEC title game. Clemson, Georgia and Oklahoma are almost certain locks. The fourth spot will probably be decided between Alabama and Ohio State, with Pac-12 champion Southern California a longshot.

“It’s not in my hands,” defensive end Tyquan Lewis said. “I’m going to leave it up to the committee. I’m going to sleep very well because I’m a Big Ten champion. I’m going to celebrate this win and if they don’t put us in, we’re going to go out a Big Ten champion still.”

If the Buckeyes get in, they’ll likely play Clemson, which beat Ohio State 31-0 in the Fiesta Bowl and then beat Alabama to win the 2016 national championship.

“I don’t care who we play,” Lewis said. “I just want to win a national title.”

Defensive end Sam Hubbard noted the significance of knocking off an undefeated team.

“Winning a conference championship is a huge deal, beating the only undefeated team (in the Power 5) in the country — we made our case,” defensive end Sam Hubbard said. “We’re playing great football right now. I don’t see why we wouldn’t get a shot.”

Lewis’ defensive linemate Nick Bosa would welcome a rematch against Clemson.

“That would be just perfect,” Bosa said.

But he said the Buckeyes have not spent much time this year hoping for another crack at Clemson.

“We really haven’t thought about Clemson, in particular,” Bosa said. “We obviously just want to get in the playoffs. If we’re in, we have a chance, and that’s all we need.”
