For the first time since 2015, four Power 5 conference champions have been selected for the College Football Playoff.
No. 1 LSU will face No. 4 Oklahoma in the Chick-fil-A Peach Bowl in Atlanta, and No. 2 Ohio State will play No. 3 Clemson in the PlayStation Fiesta Bowl in Glendale, Arizona, as decided by the CFP selection committee Sunday.
Both semifinal games will take place Dec. 28. The College Football Playoff National Championship will be held Jan. 13 at the Mercedes-Benz Superdome in New Orleans.
LSU (13-0) reclaimed the No. 1 ranking with its 37-10 win over Georgia on Saturday in the SEC championship game. The victory was the Tigers' fifth over an Associated Press top-10 team this season, which ties a record in the AP Poll era (since 1936) for most top-10 victories in a single season.
"Our goal was to go to the SEC championship and win it; that was one of our goals," LSU coach Ed Orgeron told ESPN on Sunday. "... But we're not done yet. That wasn't our final destination. I'm very proud of our offense, I'm very proud of our defense and all our coaches, but we still have some work to do."
Being the top-ranked team again might not faze Orgeron, who said he didn't care about being No. 1 or No. 2.
"It didn't matter to us," Orgeron said of his Tigers' ranking. "Anytime, anywhere, anybody -- we're ready to play. We're gonna be playing Oklahoma, a great football team.
"Wherever they tell us to play, we're gonna show up and we're gonna be ready."
Ohio State (13-0) maintained its 19-game winning streak with a second-half comeback against Wisconsin in the Big Ten championship game Saturday. Quarterback Justin Fields said the early adversity against the Badgers "made us stronger," while star defensive end Chase Young said it proved the Buckeyes were "a No. 1-worthy team."
The Buckeyes are making their and the Big Ten's first playoff appearance since 2016. Ohio State won the inaugural playoff in 2014.
Clemson (13-0) is in the playoff for the fifth straight year, winning the national title in 2016 and 2018. The Tigers haven't lost since the 2017 season, racking up their 28th straight win with a 62-17 blowout of Virginia in the ACC title game Saturday.
Swinney: This is the most complete Ohio State team we've played
Dabo Swinney commends Justin Fields and Ohio State on their talent and expresses his excitement about facing them.
But this year's résumé has been questioned after the Tigers rolled through a weak ACC and a schedule that contains just one team in the final CFP Top 25, with Virginia coming in at No. 24 after its 45-point loss.
It's a situation that has frustrated coach Dabo Swinney, who said last week that the ACC doesn't get enough credit and that Clemson is held to a higher standard.
He continued to make light of the situation Sunday, telling his team it was the first to start the season No. 1, go undefeated through the regular season and be ranked third.
"So congratulations on that," Swinney told the team.
Oklahoma (12-1) was the biggest beneficiary of conference championship weekend. The Sooners' 30-23 overtime victory over Baylor in the Big 12 title game -- paired with losses by Georgia and Utah -- vaulted them into the playoff for the third straight year.
The Sooners might not be favored in their playoff game(s), but the No. 4 seed has more titles in the past five years (two) than the No. 1 seeds (0).
LSU opened as a 10-point favorite over Oklahoma, and Clemson is a 2-point favorite against Ohio State in opening lines at Caesars Sportsbook.
According to ESPN's Football Power Index, Ohio State has the best projection to win the playoff, with a 35% chance of claiming the title. LSU narrowly has the second-best projection at 29%, followed by Clemson (28%) and Oklahoma (9%).
The Pac-12 was shut out of the playoff for the third straight year. Utah entered the weekend ranked No. 5, but its case was ruined by a 37-15 loss to Oregon on Friday. Oregon (2014) and Washington (2016) remain the conference's only representatives in the six-year history of the playoff.
