John Chayka
John Chayka (born June 9, 1989)[1] is the former general manager of the Arizona Coyotes of the National Hockey League (NHL).[2] Prior to joining the Coyotes, Chayka was part of an analytics company called Stathletes, and completed his education at the University of Western Ontario's Ivey Business School.[5] Chayka abruptly resigned from his position on July 26, 2020, just one day before the start of the 2020 Stanley Cup playoffs.NHL Commissioner Gary Bettman cited "conduct detrimental to the league and game", and further ruled that Chayka had "breached his obligation to the club" by pursuing opportunities with other clubs while still under contract with the Arizona Coyotes, and then terminating his contract with three years remaining.[7] Chayka and the Coyotes were later revealed to have hosted a private scouting combine for draft prospects, which is strictly forbidden by the NHL.
