Football Scoop (sometimes reputable, sometimes not) reports that friction has occurred between Urban and athletic leadership (Gene Smith). Friction occurs in most workplaces, so I don’t know if there’s anything to this. 

EDIT 10/23: Urban addressed (shot down) these rumors in the B1G teleconference. See here: https://www.elevenwarriors.com/ohio-state-football/2018/10/98069/big-ten...
