The Colorado Avalanche got dragged into a defensive slog Wednesday night with the Los Angeles Kings, but having more world-class players than the other team works in those types of contests, too. Mikko Rantanen had a natural hat trick and an assist, Nathan MacKinnon extended his NHL scoring lead to its greatest margin of the season and the Avs shook off another slow start to grind out a 4-2 win against the Kings at Ball Arena. “Our guys don’t need too much to make a goal,” said Avs goalie Alexandar Georgiev, who only needed to make 13 saves.
