Chasen Johnson’s road back to USC has reached a notable checkpoint.
The redshirt sophomore cornerback, who was expected to battle for a starting role in the secondary last season, is showing clear signs of progress after a knee injury derailed what could have been a breakout year. Johnson arrived from UCF as one of the more important additions in the spring transfer portal window last year, but the injury he suffered after the first week of fall camp kept him out of the season opener and eventually limited him to just two games in 2025 after surgery.
That recovery has been a long one, and USC cornerbacks coach Trovon Reed has been right in the middle of it. Reed, who coached Johnson during his freshman season at UCF in 2024, has stayed closely involved throughout the process.
In the spring, Reed said Johnson and Jontez Williams - who is also coming back from a significant knee injury - spent a lot of time in his office working through the mental side of recovery. At times, Reed said, they were even waiting there before he got in.
Johnson has kept fans updated along the way by posting clips on social media since March, showing his work on the field and in the weight room. His latest update was the most encouraging yet: a video posted to his Instagram story last Friday showed him squatting 405 pounds for three reps. Even more notable, he was doing it without a brace or sleeve on that knee.
USC is on holiday break this week, but Johnson appears to be trending in the right direction as the Trojans move toward the final stretch of summer workouts with strength coach Trumain Carroll.
His return matters because the cornerback battle is shaping up to be one of the most interesting competitions in fall camp, and one that won’t be sorted out by the season opener.
Johnson brings size to the position room at 6-foot-1 and 195 pounds, along with a physical style of play. He started four games as a true freshman under Reed at UCF in 2024.
Marcelles Williams, a former four-star recruit in the 2024 class out of St. John Bosco (Calif.), made his first career start against Purdue in week 3 last season and held onto the job. He’s also stepped into more of a vocal leadership role entering his third year with the program.
“Marcelles has improved a lot,” said USC coach Lincoln Riley in March. “I think this stretch of practice is the best ball that he's played. He's getting stronger and faster, and his body is just continuing to mature.”
Jontez Williams is the most experienced cornerback in the group, with 32 career games under his belt. The Iowa State transfer came into the portal cycle rated as the No. 1 cornerback and earned second-team All-Big-12 honors in 2024 after picking off four passes.
The room also includes redshirt freshman RJ Sermons, a former five-star recruit and talented high school sprinter with good size. Freshman Elbert “Rock” Hill arrived as ESPN’s No. 1 cornerback in the 2026 cycle. Brandon Lockhart, Jayden Crowder and Oklahoma State transfer Carrington Pierce round out the depth.

Notre Dame Just Turned Up Pressure On USC In A Crucial Fight
June brought a wave of commitment drama across the 2027 recruiting class, and Notre Dame emerged with one of the loudest hauls in the country. Marcus Freemans program, already sitting near the top of the national board, added enough high-end talent to keep the Irish in the thick of the future roster race, while USC spent much of its own 2027 work earlier in the spring and enters the summer with a class that still has real traction under Lincoln Riley.
For the Trojans, the bigger issue is not just where they stand now, but how the battle around them keeps shifting. USC has already built around notable blue-chip names across the 2026 and 2027 cycles, yet the Irish are making it clear they intend to stay aggressive in the same recruiting lanes. With the two programs not set to meet on the field for at least the next few seasons, the rivalry is going to be fought less in a stadium and more on the trail where every elite commitment matters.

Eric Musselman Just Framed USCs Biggest Rebuild Gamble
Eric Musselman is making it clear that USCs rebuild is going to be built the hard way, with a little of everything. In a college basketball era defined by constant player movement, he said the Trojans have to keep key returners, bring in high-upside freshmen and still stay active in the transfer portal if they want to keep pace. Its the sort of balancing act that has become unavoidable, but for USC it also doubles as the blueprint for how quickly this next roster can turn into something real.
The good news for the Trojans is that there is a foundation to work with, anchored by a core group from last season and a highly regarded incoming class. Christian Collins gives USC a five-star headliner, and the Ratliff twins add more talent to a class that already has people around the program thinking big. Musselmans challenge now is less about explaining the plan and more about making sure the mix of retention and additions actually holds together once the season starts. [Read more 🡒]
