USC keeps making noise on signing day under head coach Clay Helton. A few hours after landing ESPN 300 outside linebacker Levi Jones, the Trojans picked up ESPN 300 offensive tackle Austin Jackson and ESPN 300 defensive tackle Jay Tufele within minutes of each other.
Jackson selected USC over Arizona State and Washington and, along with ESPN 300 offensive tackle Alijah Vera-Tucker, gives USC two top-10 offensive tackles. Jackson is the No. 1 prospect in the state of Arizona and becomes the first top prospect from that state to sign with USC since defensive end Devon Kennard in the 2009 class.
