Make it five goals for Matt Duchene in his past four games. The talented center helped the Colorado Avalanche get back on the winning track with a goal and an assist in a 4-2 victory over the Sabres in Buffalo Saturday night. Duchene has seven points in his past four games. Gabriel Landeskog and Ryan O'Reilly matched Duchene Saturday, each producing a goal and an assist in Buffalo. Paul Statsny also scored for the Avs, who bounced back from their first loss of the season against Detroit on Thursday. The Avalanche scored four times in the first 32 minutes and that was more than enough against a Sabres team that has not scored more than three regulation goals all season.
