From an article in Slate:
There is—or more accurately, was—one notable exception: Nick Rolovich, the head coach that Washington State fired Monday after his monthslong refusal to take the shot. Rolovich was the only head coach among 130 Football Bowl Subdivision teams (and 32 NFL teams, for that matter) to acknowledge in public that he hadn’t gotten the vaccine. Rolovich had until this week to comply with Washington Gov. Jay Inslee’s
vaccine mandate for state employees. He applied for a religious exemption, which a committee reviewed blindly and
provisionally approved. But Wazzu athletic director Pat Chun, after consulting with HR and safety officials, decided Rolovich could not perform his duties without threatening public safety. Chun fired Rolovich for cause, which could be the start of a legal saga between the coach and his former school.
