USC football coach Lincoln Riley offered an impassioned defense of his recruiting tactics following the suggestion from Pittsburgh coach Pat Narduzzi that he may have tampered when wide receiver Jordan Addison transferred to the Trojans.

Addison, an All-American and Fred Biletnikoff Award winner in his sophomore season at Pittsburgh, transferred to USC in May. Pittsburgh suspected USC may have been tampering ahead of the star wide receiver’s transfer.

At Pac-12 media days last week, Riley defended himself.
