Bernard Muir led Stanford athletics in the Cardinal’s leap to the Atlantic Coast Conference after the implosion of the Pac-12. A new athletics director will be at the head of the department in Stanford’s second year in the North Carolina-based conference.

Stanford athletic director Bernard Muir will resign after 13 years on the job. Muir announced his decision on Tuesday to step down at the end of the academic year, saying it was an honor to serve in the role for more than a decade.

Barely more than 24 hours after news of his impending departure became public, Stanford athletic director Bernard Muir acknowledged his department was “slow to adapt” to the new landscape in college sports.
