Billy Donovan is reportedly stepping down as head coach of the Chicago Bulls, according to ESPN’s Shams Charania. Despite the Bulls’ interest in retaining him, Donovan chose to leave following thorough discussions with team ownership. With an earlier overhaul of their front office, the Bulls face the challenge of restructuring their leadership. Donovan, who has a history of collegiate success and a mixed NBA record, may quickly garner attention from both professional and college teams.
