SEATTLE — Turquoise towels were draped over the seats eight hours before puck drop in a city buzzing for the occasion. The party favors will be mementos in Pacific Northwest homes for years to come. Their inscription, along with a Stanley Cup Playoffs logo: “The legend awakens.” But in the Seattle Kraken’s first-ever home playoff game, the Avalanche’s sleeping giants awakened instead. Nathan MacKinnon, Cale Makar and Mikko Rantanen combined for five goals in a 6-4 series-tilting win for the Avs on Saturday night.
