The Lightning believe they can accomplish the feat, but not if they play 60 minutes the way they did in Game 5.
"That wasn't our best game, especially in the battle way," defenseman Erik Cernak said. "We lost a lot of battles. That usually doesn't happen to us."
Tampa Bay will need to limit its penalties. The Lightning were guilty of three minor penalties in a span of 7:43 in the first period after forward Ross Colton scored 53 seconds into the game to give them a 1-0 lead. They killed them all off, but it hurt the momentum they were hoping to gain from the early goal.
The Panthers scored twice in the second period to take a 2-1 lead, and made it 3-1 with a power-play goal from Patric Hornqvist 35 seconds into the third period, with Lightning defenseman Luke Schenn in the box for holding Anthony Duclair.
"We play this game 5-on-5, we're fine with it, but you just can't keep giving teams the power plays we're giving them," Cooper said. "You're basically giving them one goal a game if you're going to give them that many power plays, but it's the momentum shifts and the guys that don't get on the ice that you want on the ice. We have to do a better job with that."
Each team has scored 10 goals at 5-on-5, but the Panthers have a 54.8-45.2 advantage in shot attempts percentage (SAT) and a plus-18 edge in shots on goal at 5-on-5 (144-126).
Tampa Bay scored three power play goals in Game 1, a 5-4 win. They scored two in Game 3, a 6-5 overtime loss, and two in Game 4, a 6-2 win, and are hoping to be better at 5-on-5.
"We've got to play with a little bit more pace," Hedman said. "I think we can do a better job of moving the puck quicker and getting in on the forecheck. That's when we're at our best, when we hound pucks down and retrieve in the offensive zone and go to work in there."
That likely will come down to outworking their opposition, the biggest area of improvement the Lightning are seeking in Game 6.
"There's a little onus on the player," Cooper said. "They don't need the coach for that."
