Miles was placed on administrative leave on March 5, 2021 due to an investigation of inappropriate conduct with female students while at LSU. On March 8, Miles and Kansas mutually agreed to part ways in the wake of the misconduct allegations. USA Today's Dan Wolken wrote that the decision to place Miles on administrative leave was "merely a placeholder" until lawyers could decide whether his ouster would be deemed a mutual agreement to part ways or a firing. Along similar lines, Yahoo! Sports' Pete Thamel said the manner of his departure was "mere semantics."
