Once it got to 6-0, I couldn't help but be reminded of this exact same game (in essence) from the 2017 playoffs, when the ECF was tied at 2, Game 5, and the Penguins throttled the Sens 7-0 in Pittsburgh to take a 3-2 series lead. What happened next? Ottawa scraped out Game 6, tied Game 7 late in the third period, and it took into double overtime for the Penguins to finally knock off Ottawa once and for all. The point being that the Islanders surely still have a lot of fight left in them, that a loss is a loss whether it's 1-0, 8-0, or somewhere in-between, and that Game 6 is still going to be very tough. Pretty much what should've been expected no matter the outcome tonight.
It doesn't help that the Lightning don't have a rosy history when up 3-2 in this round of the playoffs. Their record in ECF "close-out" games since 2015 is 2-6. They've blown two 3-2 leads before. They won this exact game in the same circumstances in 2018 against Trotz's Capitals, and then didn't score another goal.
Hopefully this year is more like 2020, but still a long way to go and a lot they need to do to make that happen.
