John Mitchell's face looks like a mask. Absorbing a puck to the forehead did the most damage in a 4-0 victory over the Columbus Blue Jackets Thursday night, but incidents in Colorado's two other games messed up his nose and mouth. "I've never seen a guy three games in a row take such a beating," Avs defenseman Erik Johnson said. Looks aren't deceiving. The Avs' new third-line center is contributing to his team in multiple ways. His two goals are tied with Matt Duchene and P.A. Parenteau for the team lead, and he's tied for second with a plus-3 rating. "Obviously he's a pretty tough guy," Avs veteran right winger Milan Hejduk said.
