USC finished No. 1 in Rivals’ national recruiting-class rankings.
Martin secured signing day commitments from Long Beach Poly High cornerback Iman Marshall and Gardena Serra linebacker John Houston and defensive lineman Rasheem Green. He assisted with the recruitment of several other players, Rivals reported.
Marshall chose USC over Florida State, Louisiana State, Michigan, Notre Dame and UCLA.
Last year, cornerback Adoree’ Jackson, receiver JuJu Smith and offensive lineman Damien Mama committed to USC on signing day. Martin recruited all three.
