Entering this season with the return of star quarterback Jayden Maiava, who led the Big Ten in passing last year and is an underrated contender for the Heisman Trophy, the Trojans also return an experienced offensive line to protect him.Key returners for the Trojans' offensive line that look to provide consistent protection for Maiava this season include left tackle Elijah Paige, offensive guards Tobias Raymond and Alani Noa, right tackle Justin Tauanuu, and center Killian O’Connor. The Trojans also bring in one of the top offensive line recruits in the 2026 recruiting class with the addition of Keenyi Pepe. The 6-foot-7, 330-pound offensive tackle out of IMG Academy in Bradenton, Florida, is rated as the No. 5 player nationally and the No. 1 offensive tackle in the 2026 recruiting class. With his talent, it’ll be interesting to see how quickly of an impact Pepe will have on the Trojans' offensive line this season. Fall camp will provide an early look at Pepe’s potential. Last season, the Trojans' offensive line was among the best in the country in preventing sacks, a strength they look to build on this season.Didn’t Improve: LinebackersDec 30, 2025; San Antonio, TX, USA; Southern California Trojans linebacker Desman Stephens II (23) celebrates against the TCU Horned Frogs in the second half during the Alamo Bowl at Alamodome.

While the Trojans did bring in Washington Huskies transfer linebacker Deven Bryant, the group remains the most inexperienced on USC’s roster. Key returners at linebacker for the Trojans include Desman Stephens II and Jadyn Waker. Ta’Mere Robinson and Elijah Newby are also key depth pieces at linebacker for the Trojans entering the season. The performance of Stephens and Walker is key for the Trojans' linebacker room, as the two must be leaders at the position. Last season, Stephens and Walker finished the season combining for 122 total tackles, one forced fumble, and one sack for the Trojans.
