"It was one of those nights where I wanted the puck, I wanted to utilize my speed and creativity," Stamkos said. "It was nice to see it work. It doesn't always work but it was nice to see it happen."
Troy Brouwer and Aleksander Barkov scored for Florida (8-8-3), which is 2-3-0 on a six-game road trip.
"We've got to tighten up in the [defensive] zone a little bit," Hoffman said. "We can't be giving up that many goals and expect to win games. We have to be on top of our game against these guys and we weren't."
Kucherov gave the Lightning a 2-1 lead at 9:22 of the first period with a power-play goal from the right face-off circle, a one-timer off a pass from Victor Hedman. He beat Panthers goalie Roberto Luongo on the glove side.

Yanni Gourde made it 3-1 at 2:37 of the second at the right post off a pass from Stamkos through the goal crease, and Adam Erne made it 4-1 at 4:45 by backhanding a rebound.
"Right from the first shift until the end of the game I thought we played good," Gourde said. "We've struggled in the first period the last few games but I think we fixed that tonight and came out very strong."
Barkov pulled Florida within 4-2 with 1:35 left in the second period with a power-play goal from just outside the crease.

"Some guys need to step up, I need to step up and play better," Panthers forward Jonathan Huberdeau said. "We've just got to play and win some games."
Stamkos pushed the Lightning lead to 5-2 at 1:30 of the third period. McDonagh made it 6-2 at 3:21, and Dan Girardi scored at 14:25 to make it 7-2.

"It's tough to lose when you score seven," Domingue said. "We were opportunistic and scored some big goals at key moments. I just thought we played a great game from start to finish."
Mathieu Joseph gave Tampa Bay a 1-0 lead 59 seconds into the first period. Brouwer answered to make it 1-1 at 2:19.

Luongo had 22 saves on 28 shots before being pulled at 3:21 of third period. James Reimer made four saves on five shots.
"That was a tough game for them because they've been on the road for a long time," Lightning coach Jon Cooper said of the Panthers. "They were probably a little bit tired. And you have to take advantage of teams when they are tired because they are going to take advantage of you."

They said it
"We kind of let [Luongo] out to dry there. I thought we found our legs a little bit in the second. I thought we pushed back but ultimately they were coming in waves at us all game and we didn't have a response." -- Panthers defenseman Aaron Ekblad
"He was amazing tonight. He was winning puck battles. He was so fast. He was shooting the puck. It was a great game for him and it was really fun to play with him tonight." -- Lightning forward Yanni Gourde on Steven Stamkos
