Peter Mueller's return to the Colorado Avalanche and Jean-Sebastien Giguere's return to his old playoff form have given the Colorado Avalanche reason to believe they can do some heavy damage to the rest of the NHL down the stretch. Mueller had the go-ahead goal in the fifth game of his inspirational comeback from a concussion, Giguere made 25 saves and the Avalanche also got goals from Cody McLeod and Gabriel Landeskog in a 3-1 victory over the Los Angeles Kings on Saturday night.
