Mike Bohn announced a sudden resignation from his AD post at USC Friday afternoon, citing “ongoing health challenges” and a desire to focus on time with his family. However, his abrupt decision is also reportedly tied to other issues.

According to Ryan Kartje with The Los Angeles Times, Bohn’s resignation came a day after Bohn was questioned by The Times about internal criticism of his management of the Trojan athletics department. Kartje also reported multiple employees that cited staffers inside the department raising concerns about Bohn:

Four current and former USC employees said that staffers inside the athletics department had raised concerns to the law firm about Bohn.

Most reviews of Bohn’s time with the Trojans were positive for his impact on leading USC into the B1G. He also helped stabilize the football program by luring Lincoln Riley away from Oklahoma last offseason.

It will be interesting to see if more comes out about Bohn related to his time at USC and the abrupt move to resign.
