While both Tippett (who signed a five-year contract extension in June of 2013), and Maloney are signed to long term contracts, it was while the team was being operated by the NHL. IceArizona is the current ownership group, and they get to decide the fate of both Tippett and Maloney, should the need arise.
I’m not sure what parameters were agreed to when IceArizona took over, but the contracts were signed, and should be binding. The question which remains is, what happens if the Arizona Coyotes have another disastrous season, and fail to make the playoffs once again?
