O'Donoghue is an intelligent player that can carve out a role for himself with astute positioning and shot blocking.
O'Donoghue enters the second season of his two-year entry-level contract in 2015-16 after splitting time between the AHL and ECHL last year. He will look to play with the Coyotes' new AHL affiliate in Springfield on a full-time basis this season. More will be known about his long-term pro potential following this season.
