The Lightning likely will go with what worked against the Bruins, matching Brayden Point's line, with wings Ondrej Palat and Tyler Johnson, and defensemen Anton Stralman and Ryan McDonagh, against the Capitals' top line of Ovechkin, Evgeny Kuznetsov and Tom Wilson.
Tampa Bay's shutdown group held the Bruins' top line of Patrice Bergeron, Brad Marchand and David Pastrnak without a 5-on-5 goal in the final four games of the series. Point, Palat and Johnson combined for seven.
"The one thing I think Point, Palat, Johnson, those guys, had to get out of their head was that they had to outscore the other line," Lightning coach Jon Cooper said. "The big thing is don't let them score, and then whatever happens after that, happens."
