One down, two to go.
USC went into Wednesday's national signing day hoping to land Bellflower St. John Bosco offensive lineman Damien Mama, Long Beach Poly receiver/defensive back John "Juju" Smith and Gardena Serra receiver/defensive back Adoree' Jackson.
Mama announced he would attend USC and the school announced he had signed a letter of intent.
The 6-foot-5, 370-pound Mama is the second player from undefeated St. John Bosco to sign with the Trojans, joining defensive end/linebacker Malik Dorton.
"Damien is a massive guy, but for how big he is, he carries his weight really well," USC Coach Steve Sarkisian said on USC's website.
"He is a force in the interior of the line, and the kind of guy you love to run behind."
