Over the course of his four seasons as coach of the USC Trojans, Lincoln Riley has had several transfers that have made an impact. Entering a make-or-break 2026 season for Riley and the Trojans, USC has several transfers that look to lead the team to its first appearance in the College Football Playoff. There is one transfer, however, who is gaining attention for the Trojans as they enter the 2026 season. According to CBS Sports, former Michigan State Spartans defensive tackle Alex VanSumeren is the one transfer that could wing the Trojans CFP aspirations.

With new defensive coordinator Gary Patterson, the Trojans defense is looking to improve against the running game, and the addition of VanSumeran can help that. It's an aspect that has been missing from the Trojans defense the last few seasons and proved costly in their three regular-season road losses last season against the Illinois Fighting Illini, Notre Dame Fighting Irish, and the Oregon Ducks, keeping USC out of the CFP.

With a player like VanSumeran, who excels at finishing tackles and winning matchups against premier offensive linemen, the Trojans' rush defense should take a step forward next season. Last season, the Trojans' rush defense ranked 81st nationally, allowing an average of 143.2 rushing yards per game.

Players that are set to join VanSumeren on defense include Penn State Nittany Lions Edge rusher Zuriah Fisher, Iowa State Cyclones cornerback Jontez Williams, Washington Huskies linebacker Deven Bryant, Georgetown Hoyas linebacker GianCarlo Rufo, and Oklahoma State Cowboys cornerback Carrington Pierce.The Trojans 2026 transfer portal class is ranked No. 29 overall and seventh in the Big Ten, per 247Sports.

The Trojans' first four games of the season set up nicely for USC to get off to a strong start before a marquee home matchup against the Ducks on Sept. 26. In addition to the season opener against San Jose State, USC will face the Fresno State Bulldogs (Sept. 4), the Louisiana Ragin Cajuns (Sept. 12), and the Rutgers Scarlet Knights (Sept. 19).
