WINNIPEG — The margins are never thinner, and the swings are never greater than in the Stanley Cup Playoffs. The Colorado Avalanche was centimeters from a potentially back-breaking goal and about 27 minutes from a 2-0 series deficit Tuesday night at Canada Life Centre. A few minutes later, the Avs had control of the game and a period later had stolen home-ice advantage from the Winnipeg Jets in this opening-round series. Artturi Lehkonen, Zach Parise and Josh Manson scored during a potentially series-shifting flurry late in the second period, and the Avalanche claimed a 5-2 victory in Game 2 to even this best-of-seven series at one game each.
