Although the Avalanche portrayed the Wednesday acquisition of Swiss goalie Reto Berra from Calgary as "insurance," it's safe to say that Colorado wouldn't have been bothered if Jean-Sebastien Giguere interpreted it as a challenge to return to his strong early-season form as Semyon Varlamov's backup. Giguere played well in his second start since the Olympic break Thursday night, making 35 saves, and the Avalanche got a goal from Andre Benoit at 4:29 of overtime to claim the 3-2 victory over the Detroit Red Wings at Joe Louis Arena. Matt Duchene had a goal and an assist and rookie Nathan MacKinnon's consecutive-game point streak reached 13 when he got an assist on Benoit's goal. He surpassed Wayne Gretzky for the longest point streak by an 18-year-old. Berra didn't join the Avalanche in Detroit, and there's a chance immigration issues will additionally delay his arrival in Denver. Because the 27-year-old Swiss had been playing for a Canadian franchise, the Calgary Flames, his trade to a U.S.-based team involved a new batch of procedural complications. So for at least one more night, Giguere was the only backup option as coach Patrick Roy gave Varlamov a game off at the approach of Saturday afternoon's Central Division showdown with the St. Louis Blues at the Pepsi Center. On Thursday, Roy indicated the plan was to keep all three goalies around for the rest of the season, that Varlamov would play about "75 percent" of the games, and that both Giguere and Berra would get some work. Detroit defenseman Nicklas Kronwall opened the scoring, lifting a backhander over Giguere's shoulder at 12:33 of the first period. Colorado tied it on Duchene's 20th goal of the season at 10:11 of the second. Erik Johnson's shot went off Kronwall's skate, off the end boards to Duchene in front, and he barely got his stick on it. But the puck slid off the skate of Red Wings' forward Johan Franzen and in.
