Four-star cornerback commit Isaiah Rubin makes it official, signs with USC

Back during the early signing period in December, local four-star cornerback Isaiah Rubin was the only USC commit to not formally sign with the program.

On Wednesday, he made it official.

Rubin continues the Trojans' strong close to the 2024 class, pushing USC's total of commits to 22 and is one of three additions to ink their National Letters of Intent to kickoff the late signing period along with three-star defensive lineman Ratumana Bulabalavu, who initially signed with Washington but got his release after the coaching shakeup there, and three-star linebacker Jaydn Walker, who flipped from Michigan State.

Rubin, from Los Alamitos High School, gives the Trojans five intriguing defensive backs in this class, along with fellow four-star cornerbacks Braylon Conley and Marcelles Williams, four-star safety Jarvis Boatwright and three-star safety Marquis Gallegos. The other four enrolled last month and will go through spring practice while Rubin will join the team this summer.

Rubin committed to USC back in October, telling TrojanSports.com at the time that he had dreamed of playing for the Trojans since he was 7 years old.

"Me and my pops growing up watching SC games," Rubin said. "He'd been to the SC games when he was a little kid. Me and him, we just have that connection with SC and just wanted to make it happen."

Rubin was recruited by former cornerbacks coach Donte Williams, but Williams' departure to Georgia in December didn't ultimately make a difference as Rubin followed through on his USC pledge.
