Though the Amat to USC pipeline was dormant until 2016 with the signings of four-star receivers Tyler Vaughns and Trevor Sidney, it is one of the most historical pipelines in school history.
During the John McKay Era, Amat was a breeding ground for USC, including national championship quarterbacks Pat Haden and Paul McDonald, along with the coach’s son himself, J.K. McKay. The trio all became entrenched in the Trojan family, as athletic director, associate athletic director and color commentator.
Years later, it was revived during the Larry Smith years, as the Trojans went to three-straight Rose Bowls with Lancer star John Jackson on the roster, who ironically replaced McDonald on USC’s radio broadcasts.
