It's Feb. 1, but the last time the Avalanche will play in Denver until Feb. 26. Colorado's four-game trip through New York and Philadelphia precedes the NHL's shutdown for the Olympics in Sochi, Russia.

The likely playoff-bound Avs wanted a good a send-off Saturday, and despite playing with just 11 available forwards because of injuries to Paul Stastny and Alex Tanguay, they got that and much more.

Behind two goals apiece from Gabe Landeskog and Jamie McGinn and scoring from all four lines, they pounded the Buffalo Sabres 7-1 at the Pepsi Center to improve to 8-2 in their last 10 games and 19-7-3 at home.

Landeskog and McGinn highlighted the rare rout and rookie Nathan MacKinnon was again extraordinary — and not just because he's 18. MacKinnon played like the NHL All-Star that he could have an opportunity to become next year, when the mid-season classic resumes in a non-Olympic year.

MacKinnon had two primary assists before scoring his 20th goal to tie Ryan O'Reilly for the team lead. MacKinnon is the seventh Avalanche rookie to score 20 goals, and by far the youngest. His goals, power-play goals (eight), and points (40) are most among rookies as he continues his assault for the Calder Trophy in a year the other top contenders are in their early to mid-20s.

Tyson Barrie, McGinn, Landeskog and Marc-Andre Cliche scored as Colorado built a 4-0 lead and coasted by a Sabres team that features former Avs coach Joe Sacco, now an assistant under interim boss Ted Nolan.
