Lincoln Riley Just Spotlighted A New Answer To USC's Biggest Flaw

Coach Lincoln Riley touts new defensive powerhouse Alex VanSumeren as a key player in USCs ambitious rebuild for 2026.

Lincoln Riley didn’t hide how much he likes what USC added in the trenches this offseason, and one name kept coming up in Chicago on July 28: Alex VanSumeren.

Speaking at the annual Big Ten Conference Media Days at Hilton Chicago, Riley pointed to the Trojans’ strong 2026 haul - a class that ranked No. 1 nationally - and the transfer help that came with it. VanSumeren, the lone 2026 portal addition Riley brought up, clearly stood out to him.

“Alex VanSumeren [was] one of the guys we identified once he jumped in the portal in terms of not only his experience, but his play style and his leadership capability,” Riley explained to reporters. “Having a leader or bell cow that has experience and that type of mentality that Alex does is very, very key.”

The 6-2, 295-pound defensive tackle arrives from Michigan State with production and a reputation for doing the dirty work inside. He finished with 52 total tackles and two stops behind the line of scrimmage, and in 2024 he added 16 tackles and 2.5 for a loss in East Lansing, Michigan.

For USC, that kind of presence matters. Riley admitted the Trojans didn’t defend the run well last season, and VanSumeren looks like the type of body and temperament they wanted to help fix it.

The Bay City, Michigan native is also making the move far from home, but he said the pull of USC was too strong to pass up. In comments to Kendell Hollowell of USC Trojans on SI, VanSumeren said, “It's a tradition-rich program,” VanSumeren began.

“Everyone knows USC football. I couldn't turn down the opportunity to play with these teammates and with this program.”

USC didn’t bring just one interior defender to the media days stage. Defensive tackle Jide Abasiri was there too, along with quarterback Jayden Maiava. Jahkeem Stewart, another interior defender expected to take a big step this fall, was not present after spending the offseason working to sharpen his pass-rushing skills.

That group gives USC a real chance to roll out a disruptive interior front. Stewart and Abasiri are projected as the starters inside, and both bring length, energy and the ability to push through guards or even double teams. Abasiri, in particular, flashed that kind of force last season.

VanSumeren fits right into that picture. His active hands and relentless motor were already on USC’s radar before the Trojans landed him through the portal, and the staff sees him as more than just another body. He can help clog running lanes, rotate in when needed and give new defensive coordinator Gary Patterson another option in short-yardage or goal-line situations.

For a USC defense trying to get tougher up front, Riley’s praise for VanSumeren says plenty.

USC Is In A Real Fight For Elite California Linebacker

Southern Cal has stayed active with Landon Miller, and the four-star linebacker has given the Trojans plenty of reason to keep pushing. The California standout has been on campus for an unofficial multi-day visit, worked out on the field, studied film, toured campus and met with Lincoln Riley, Chad Bowden, Max Stienecker and linebackers coaches AJ Howard and Mike Ekeler, all while remaining one of the nations most closely watched defensive recruits.

Millers recruitment is still wide open, with USC in the mix against several blue-blood programs and more visits on the calendar. He plans to be at the Trojans Sept. 12 game against Louisiana, then head to Oregon for its matchup with UCLA, with additional trips to other contenders still possible as he keeps sorting through a decision that could shape the West Coast linebacker market.

Drake London Is Paying The Price For Something He Cannot Fix

Drake Londons name came up again in a familiar kind of conversation this week, the sort that says as much about circumstance as it does about talent. League executives and coaches left the former USC standout just outside the top 10 NFL receivers list, slotting him as an honorable mention instead, even though his profile keeps growing in ways that are hard to ignore.

One NFL coordinator described London as a solid possession receiver who wins contested catches and shows up in the red zone, but also pointed to the limitations around him in Atlanta. For USC fans who watched him develop into a polished playmaker, the frustrating part is how much of his ceiling still seems tied to factors he cannot control, leaving his reputation a step behind his ability.

USC Defender Is Giving Lincoln Riley A Reason To Believe Up Front

Jide Abasiris offseason became one of those quiet USC developments that can matter a lot once the pads come on. The defensive lineman arrived at the 2026 Big Ten Media Days talking less about depth-chart noise and more about the work he put in away from it, stressing personal development, confidence and the kind of day-to-day commitment that coaches notice long before the box scores do. Lincoln Riley has already singled out Abasiris dedication to the program, a meaningful nod for a player trying to carve out a bigger role up front.

Abasiri also offered a glimpse into the mindset that has shaped his path, including the way his Nigerian heritage has influenced his football journey. For USC, that matters because the Trojans are looking for more than just bodies on the defensive line - they need players who can grow into reliable pieces in a demanding league. Abasiri sounds like someone intent on being that kind of presence, even if the bigger test of how far he has come is still ahead. [Read more 🡒]
