Memorial Coliseum athlete

TROJAN

This mascot represents a university in Los Angeles known for its cardinal and gold colors and fierce rivalry with the Bruins.

The Memorial Coliseum is home to the University of Southern California (USC), whose sports teams are called the Trojans. The clue points to an athlete from USC, so the answer is their mascot name. "TROJAN" fits perfectly as both the team name and a nod to the ancient warriors of Troy, which the school uses for its branding. It’s a straightforward reference to college sports culture.
