RJ's Third USC Defender With the Most to Prove: Marcelles Williams

RJ rounds out his list of USC defensive players with the most to prove in 2026 by highlighting Marcelles Williams. While Williams graded out solidly last season, RJ explains why the numbers need to take another step forward this year. With a starting cornerback spot seemingly his to lose, Williams has a major opportunity to build on last season's experience and establish himself as a long-term fixture in USC's secondary. RJ also explains why Williams joins Kameryn Crawford and Desman Stephens as the three defenders whose development could significantly impact the Trojans' defense this season.
