USC heads into the 2026 college football season with a roster that looks loaded on paper, but the age profile tells a different story. The Trojans are the youngest team in the Big Ten by average roster age, and one of the youngest in the country.
RotoWire’s numbers put USC at 19.87 years old on average for 2026. That makes the Trojans the youngest roster in the conference and tied for 132nd youngest nationally.
A huge reason for that is the size of USC’s incoming high school class. The Trojans signed the No. 1 ranked 2026 recruiting class in the country, a group that includes 35 total commitments. Those players will arrive as true freshmen, and some of them could be in position to contribute right away.
Two five-star names stand out most: edge rusher Luke Wafle and tight end Mark Bowman.
Even with all that youth, USC won’t be leaning entirely on newcomers. Quarterback Jayden Maiava is set to be the veteran anchor.
He’s entering his fifth season in college and third at USC, and after starting for the Trojans in 2025, he threw for 3,711 yards and 24 touchdowns. Maiava is 22 years old.
At the other end of the Big Ten age chart sits Michigan State. The Spartans have the oldest average roster age in the league at 20.64 years old, which also ranks as the 15th oldest roster in the nation.
Michigan State is coming off four straight losing seasons and hasn’t won more than five games in a season since 2021. The Spartans are now led by coach Pat Fitzgerald.
Here’s how RotoWire ranked the Big Ten’s rosters by average age for 2026, from oldest to youngest:
- Michigan State Spartans
- UCLA Bruins
- Nebraska Cornhuskers
- Northwestern Wildcats
- Penn State Nittany Lions
- Rutgers Scarlet Knights
- Wisconsin Badgers
- Purdue Boilermakers
- Maryland Terrapins
- Minnesota Golden Gophers
- Michigan Wolverines
- Oregon Ducks
- Illinois Fighting Illini
- Iowa Hawkeyes
- Indiana Hoosiers
- Washington Huskies
- Ohio State Buckeyes
- USC Trojans
Oddsmakers don’t seem worried about USC’s youth. DraftKings Sportsbook has four teams with the best odds to win the Big Ten, and all four are on the younger side of the conference’s age rankings.
Ohio State is the favorite at +180, and the Buckeyes are younger than every Big Ten team except USC. Indiana has the second-best odds at +250, even though the Hoosiers rank 15th in the conference in average roster age.
Oregon sits third at +260 and checks in 13th on the age list. USC is next at +1400, and its youth doesn’t appear to be a major obstacle on paper.

USC Fall Camp Opens With One Position Battle Looming Over Everything
USCs fall camp opens with the roster in a familiar place for a program trying to climb back toward the top: plenty of talent, plenty of new faces, and more than a few jobs still up for grabs. The Trojans have mixed proven returners like linebacker Desman Stephens II and defensive lineman Jahkeem Stewart with additions such as linebacker Deven Bryant and tight end Tucker Ashcraft, giving the staff a deeper look at several spots that could shape the season.
The most intriguing part of camp may be how quickly the younger players force their way into the conversation, especially at tight end, wide receiver and in the secondary. Mark Bowman brings the kind of buzz that can change a room early, while USC will also be sorting out how its receiver and cornerback groups settle in behind the top names. For a team with real depth questions and a few potential breakout players, the first stretch of camp should reveal which position battle matters most. [Read more 🡒]
USCs 2026 Run Game Suddenly Hinges On One Troubling Question
Waymond Jordan was already positioned to be the centerpiece of USCs rushing attack in 2026 before the injury against Michigan changed the conversation around him. Even after a limited spring because of a procedure, he still looks like the most dynamic back on the roster and one of the more important leaders in the room, which is why the Trojans have spent so much time thinking about what the offense looks like with him at full strength.
King Miller is the next name up if Jordan is not available, with Riley Wormley, Deshonne Redeaux and Shahn Alston also in the mix behind him. USC has enough bodies to keep the backfield moving, but the bigger question is whether any of them can match the steadiness Jordan has already shown in the situations that matter most. [Read more 🡒]
USC Legends Are Surrounding This Program And Recruits Can Feel It
USCs recruiting pitch has always leaned on tradition, but this spring and summer it has felt more tangible than nostalgic. Former Trojans such as Marcus Allen, Willie McGinest, Mike Williams and Ronnie Lott have not just been name-dropped around the program, they have shown up, sat in on games, spoken to recruits on official visits and taken part in team events. For current players and visitors, that means the history is not sitting in a trophy case somewhere. It is walking the sideline, shaking hands and reinforcing what it means to wear the jersey.
The effect matters because recruits notice who is around when they are being asked to imagine their next three or four years. Allen, McGinest and Lott have each had chances to connect with young players, while recent USC stars have also been visible around offseason work and spring practice, adding another layer to the message. For a program trying to keep its momentum in recruiting, the presence of so many familiar faces gives the pitch extra weight, and it is part of why the Trojans can sell more than a depth chart and a facility tour.
