CFP quarterfinal first look: X factors, key players and how each team can win

Beginning with snow in South Bend, the College Football Playoff made its on-campus debut this weekend. The scenes have not disappointed.

Up next is the quarterfinal round, which features four games played at traditional postseason sites: the Rose Bowl, Fiesta Bowl, Sugar Bowl and Peach Bowl. Much like the first round, the quarterfinals will span two days. No. 3 Boise State kicks things off and will make its first-ever CFP appearance -- albeit in a very familiar game, the Fiesta Bowl, where 18 years ago much of the country learned about the Broncos in their unforgettable win against Oklahoma. They'll face No. 6 Penn State.

The New Year's Day slate begins with perhaps the most surprising CFP entrant: Arizona State, which was picked to finish last in the 16-team Big 12 and won the league to earn the No. 4 seed. Coach Kenny Dillingham's Sun Devils will be in the Chick-fil-A Peach Bowl for the first time since 1970. Up next will be the Rose Bowl Game presented by Prudential, in which No. 1 seed Oregon, the nation's only undefeated team this season, will take the field. An incredible day finishes up in New Orleans, where No. 2 seed Georgia, the only team in the CFP field to win a national championship in the past four seasons, will face No. 7 Notre Dame at the Allstate Sugar Bowl.

Ten teams are left in the hunt for a national championship, following a season of unpredictability. Here's a look at the first two quarterfinal matchups and what to expect Dec. 31 and Jan. 1. -- Adam Rittenberg

Vrbo Fiesta Bowl: No. 6 Penn State vs. No. 3 Boise State

When: Dec. 31, 7:45 p.m. ET. TV: ESPN

Penn State Nittany Lions (12-2)

What we learned in Round 1: Perhaps we learned Penn State has an elite defense, but that seemed pretty clear before the 38-10 win over SMU in which the D picked off Kevin Jennings three times in the first half, returning two for touchdowns. Moreover, those interceptions were as much a statement about SMU's incompetence on the execution of those plays as Penn State's brilliance. Perhaps we learned that, once again, the 106,000-plus fans in Happy Valley can create havoc for opposing teams, but that won't be an advantage through the rest of the playoff for Penn State. Perhaps we learned coach James Franklin can win a big one. He had been just 5-21 vs. top-12 teams at Penn State entering this year's playoff. But while SMU might have earned its No. 11 ranking, the talent disparity on the field clearly favored Penn State, and had the Mustangs not imploded of their own accord so early, there might've been real hand-wringing over Franklin's perplexing fourth-down call from his own 20-yard line up 14-0 or the offense's inability to break big plays against SMU until the score was entirely lopsided. In other words, Penn State's win was encouraging, because things mostly went right, and the Nittany Lions did what they were supposed to do. But beyond that, an easy victory against an SMU team that helped by beating itself didn't exactly prove that this year's Penn State is finally capable of getting over the hump against a genuinely top-tier opponent. The really good news is, the Nittany Lions are going to get at least one more chance to do just that.

X factor: QB Drew Allar. Allar and the Penn State passing game have been a mixed bag over the past two years. The top-line numbers speak for themselves. Allar wins, he doesn't turn the ball over, and he has moved the ball consistently against lesser competition. But the downfield threat has never quite materialized for Allar, even as the offense's explosiveness has improved with Andy Kotelnicki calling plays in 2024. Part of that comes from the lack of a true speed demon on the outside, and part of it comes from a game plan built around two talented tailbacks. But there will come a time in these playoffs -- and quite possibly against Boise State -- when Allar needs to change the dynamic, force a defense to respect the vertical threat and win some battles downfield.

How Penn State wins: It's unlikely Penn State can completely run back the blueprint for beating SMU, as it's not often a defense is gifted so many big plays by the opposing quarterback, but the basic framework for a win should look a good bit like what the Nittany Lions did in Round 1. It's no secret Boise State's magic is created by tailback Ashton Jeanty, so if Penn State can force the game into Maddux Madsen's hands instead, there's reason to think it can cash in on some QB mistakes, just as it did against SMU. Of course, that's easier said than done. Jeanty has faced his share of stacked boxes this season, so not only does Penn State need to game-plan to stop Jeanty on defense, but Abdul Carter, Dani Dennis-Sutton & Co. have to actually bring down the Heisman Trophy runner-up before he can escape into space. -- David Hale

Boise State Broncos (12-1)

Key player: RB Ashton Jeanty. Jeanty has turned in one of the best seasons college football has ever seen from a running back, rushing for 2,497 yards and 29 touchdowns, to finish second in the Heisman voting. He needs 132 yards to break Barry Sanders' single-season rushing record, which has stood since 1988 (when bowl stats did not count toward official stats). Jeanty can do it all: get tough yards, break long ones, catch passes. And he has done it as the focal point from opposing defenses in a way few players ever are.

X factor: QB Maddux Madsen. There isn't really a question of what the Broncos will get from Jeanty. He's going to deliver when the chances are there and, probably, when they aren't. In the Mountain West, he was dominant enough to minimize the importance of the passing game. That won't be the case in this game. The Broncos will need complementary football and Madsen to rise to the occasion. In the regular season, Madsen did an excellent job protecting the football -- he threw 29 touchdowns to just three interceptions -- and that has to be the case against Penn State. The Nittany Lions terrorized SMU quarterback Kevin Jennings, and SMU never stood a chance with his poor performance.

How Boise State wins: When the Broncos lost by three at Oregon in September, they went toe-to-toe with the Ducks from start to finish. That performance earned them a lot of credibility with the selection committee and is perhaps the blueprint for how to advance. The key part here is not falling behind early. They never trailed by more than a score against Oregon, and that allowed Jeanty to stay as involved as possible. He's going to see loaded boxes, as usual, but the opposing talent level is much higher than anything the Broncos have seen since Oregon. If Boise State can hang on to the ball and avoid third-and-long, it will have a puncher's chance. -- Kyle Bonagura

Allstate Sugar Bowl: No. 7 Notre Dame vs. No. 2 Georgia

When: Jan. 1, 8:45 p.m. ET. TV: ESPN

Notre Dame Fighting Irish (12-1)

What we learned in Round 1: Notre Dame has a championship-level defense with stars at all three levels. Safety Xavier Watts won the Bronko Nagurski Award in 2023, but he's actually even better this season and showed why against Indiana with 10 tackles and an interception. Jaiden Ausberry led a playmaking group of linebackers and Rylie Mills created havoc up front, as Notre Dame flexed on third down (7 of 13 conversions). Notre Dame's offense isn't always the most fluid unit, but with so many running options, chunk plays are always possible, and Jeremiyah Love can deliver them, as he showed with a 98-yard touchdown, the longest play in CFP history.

X factor: WR Jordan Faison, a standout lacrosse player thrust into action at wide receiver in 2023 because of attrition, has become a sneaky good target for quarterback Riley Leonard. Despite missing three early-season games with a sprained ankle, Faison has made multiple catches in every contest he has appeared in, and he had a career-high seven receptions for 89 yards against Indiana. "He's a playmaker, man," coach Marcus Freeman said. The sophomore also has a knack for shining in the postseason, as he earned Sun Bowl MVP honors last year with 115 receiving yards and a touchdown against Oregon State. Notre Dame can't beat Georgia strictly with its run game, and it will need wideouts such as Faison to make notable contributions.

How Notre Dame wins: The Irish must harass Georgia quarterback Gunner Stockton, likely filling in for injured starter Carson Beck, just as they did Indiana's Kurtis Rourke on Friday. Notre Dame's defense, which has carried the team much of the season, recorded 10 tackles for loss and three sacks against Indiana and rarely let the Hoosiers operate on schedule. The Irish also need to replicate the offensive balance they showed against Indiana while being a bit more consistent on the ground. Remove Love's 98-yard touchdown, and Notre Dame had 95 net rushing yards on 34 carries. Notre Dame also must play a cleaner game on special teams after having a field goal attempt blocked and an onside kick recovered by Indiana late in the game. -- Rittenberg

Georgia Bulldogs (11-2)

Key player: QB Gunner Stockton. With Bulldogs starter Carson Beck probably sidelined for the CFP because of an elbow injury on his throwing arm, they'll turn to Stockton, who is expected to make his first start in the Sugar Bowl. Stockton completed 12 of 16 passes for 71 yards with no touchdowns and an interception in Georgia's 22-19 victory over Texas in the SEC championship game. He came off the bench to rally the Bulldogs back from a 6-3 deficit at the half. The third-year sophomore has completed 78.1% of his attempts for 206 yards in parts of three games in 2024. Stockton is more of a runner than Beck, but he has far less experience. At Rabun County High School, Stockton had 13,652 career passing yards and 177 passing touchdowns to go with 4,372 rushing yards and 77 rushing touchdowns in his four-year career. He set Georgia state high school records for career passing touchdowns, passing yards and rushing touchdowns.

X factor: RB Trevor Etienne. The Florida transfer returned from a nearly monthlong absence because of a rib injury and ran for 94 yards with two scores in the SEC championship game. He ran for 87 yards with three touchdowns in a 30-15 victory over the Longhorns in the regular season. Etienne can become a big safety valve for Stockton because of his ability to catch the ball out of the backfield -- he has 28 receptions for 168 yards. Etienne is also a more-than-capable blocker, which will be important if Notre Dame's defense decides to dial up the heat on Stockton. The Irish are 39th in run defense in the FBS (133 yards per game), and they held Indiana to only 63 yards in the first round.

How Georgia wins: With Stockton stepping under center, the Bulldogs are going to need their defense to rise up big time. This hasn't been Georgia's best defense under coach Kirby Smart; it ranks 21st in scoring defense (20.4 points), 36th against the run (127.8 yards) and 35th in total defense (334.8 yards). The defense has played well in some of Georgia's biggest games, including wins over Texas and Tennessee. Linebackers Smael Mondon Jr. and Jalon Walker will need to control Notre Dame's running game, and they'll need to force the Irish into a couple of turnovers. -- Mark Schlabach
