Here are 5 keys for Game 4:

1. TRIPLET THREAT

Lightning coach Jon Cooper reunited his "Triplets" line of Ondrej Palat, Tyler Johnson and Nikita Kucherov in the third period of Game 3 on Wednesday and they combined for two goals in a 4-2 loss. After being outshot 89-49 in losing the past two games, the Lightning need an offensive spark. But Cooper seems reluctant to use the "Triplets" together for the full game because he wants balanced scoring from his four lines.

Cooper hinted he could use Palat, Johnson and Kucherov together in certain situations in Game 4. That's what Penguins coach Mike Sullivan has done with some effectiveness the past two games in picking his spots to use Sidney Crosby and Evgeni Malkin on the same line. Maybe using the "Triplets" similarly will be enough. But Cooper shouldn't hesitate to rely on them more if the Lightning struggle to produce scoring chances again.
