"He's the biggest competitor on this team," Lightning defenseman Victor Hedman said. "He competes really hard in practice and in games. We owe it to him to play better over 60 minutes. He's undoubtedly been our most complete player the whole year."

Chris Kunitz, Hedman and Yanni Gourde scored to give the Lightning (36-13-3) a 3-0 lead. But Thomas Vanek scored a wraparound goal at 10:00 of the third period, and Brock Boeser scored on a solo rush 4:30 later to make it 3-2 before Conacher converted the penalty shot after being cut by a high stick on a breakaway.
"I like the result but how we got there was probably not how we drew it up," Lightning coach Jon Cooper said. "You got a 3-0 lead going into the third period, and if Conacher doesn't draw that penalty shot -- and fortunately he scored -- who knows what would have happened because it wasn't looking too good for a while."
Nikita Kucherov had two assists for Tampa Bay to give him 300 career NHL points. He leads the NHL scoring race with 66 points (27 goals, 39 assists), three ahead of Phil Kessel of the Pittsburgh Penguins.
Vancouver took 33 shots, the eighth straight game Tampa Bay has given up 30 or more.
"We built a lead and that was enough, but in the end, giving up the scoring chances we gave up, and the shots, it's become a little bit of a trend," Cooper said. "We have to figure that out."
