Lightning struck twice at the Pepsi Center on Monday night. First, Avalanche first-line winger Mikko Rantanen was tripped into the end boards in the second period and didn’t return. Colorado’s highest-paid player be out “weeks” with a shoulder injury. And then the red-hot Tampa Bay Lightning got a slick breakaway goal from standout Nikita Kucherov 3:03 into overtime to extend its winning streak to 11 games, winning 4-3 in a game Colorado skated off with a well-earned point. “Their best player had a breakaway and I wasn’t able to stop it,” Avs goalie Pavel Francouz said.
