Stanford defensive line coach Randy Hart announced his retirement Tuesday after six seasons with the Cardinal and 46 years in college football in full-time capacity.

Hart, 67, who played and coached for Woody Hayes at Ohio State, made his reputation as an assistant during a long tenure at Washington in which he helped direct one of the most fearsome defenses in Pac-12 history.

“I am honored and blessed to have been at so many great places with so many fantastic coaches, student-athletes and fans,” Hart said. “And for that, I’m one of the luckiest coaches ever.

“I have loved each one of my players, and have enjoyed working with every staff member throughout the years. Everyone has to make this decision at some point in time, and this was the right time for me and my family.”

Stanford did not name a replacement or provide a time-frame for the decision.
