The New York Rangers have hired Mike Sullivan as coach. Sullivan was out of a job for less than a week after he and the Pittsburgh Penguins agreed Monday to part ways. Sullivan replaces Peter Laviolette, who was fired after the Rangers missed the playoffs following a trip to the Eastern Conference final last year. Sullivan, who coached Pittsburgh to the Stanley Cup back to back in 2016 and ’17, is tasked with trying to turn the Rangers back into an immediate contender. General manager Chris Drury made the move to get Sullivan not long after receiving a multiyear contract extension of his own.
