SUNRISE, Fla. — The Colorado Avalanche showed off its sublime collection of skill, increased depth and ability to play beautiful hockey against the defending Stanley Cup champions on Saturday night. Some of the Avs’ early-season flaws were also on display at Amerant Arena. In the end, Colorado needed a great third period from its goaltender and contributions from nearly the entire lineup to collect a 7-4 win against the Florida Panthers. It didn’t always look great, but the Avs have won seven of their last nine games and 12 of 17 since an 0-4 start. “I think we’re pretty happy with the lineup we’re playing now,” Avs coach Jared Bednar said.
