BUFFALO, N.Y. (AP) — Mike Sullivan has another souvenir to add to an already large personal hockey collection after being presented the game puck following his first victory as coach of the New York Rangers. It might not match the two Stanley Cup titles he won during his 10-year tenure as the Pittsburgh Penguins coach, but the significance of the 4-0 victory over Buffalo wasn’t lost on Sullivan on Thursday night. “It’s humbling,” said Sullivan, who is from Massachusetts and the only U.S.-born coach to win at least two Cups.
