The Avalanche had scored a power play goal in a dozen consecutive games. In the unlucky 13th, they got played by their own power play. Nathan MacKinnon’s shot was blocked, Cale Makar’s recovery of a bouncing puck was squandered at the blue line, and Frederick Gaudreau converted the ensuing short-handed breakaway for the back-breaking goal in Colorado’s 4-2 loss to the Wild on Wednesday. “I was going backward for the first little bit, and then just couldn’t get back,” Makar said.
