"As a Hall of Fame coach, who is one of the game's most highly regarded defensive minds, he brings a wealth of success and experience to our program. His impact will be immediate, elevating our defense and strengthening the culture we've built. We're proud to welcome him to the Trojan Family." Patterson was the defensive play caller as TCU's head coach, and he ran a unique 4-2-5 defensive scheme that used a versatile nickelback.
