No, the Islanders may not be nearly as talented as Tampa Bay. But the Islanders are extremely well-coached and have proven resilient since play resumed. 
New York outshot the Lightning, 28-21, and had numerous missed scoring opportunities in a 2-1 Game 2 loss. 
So I don't see the Islanders quietly going in the night down 0-2 in the series. They are in must-win territory and draw Tampa Bay minus suspended right winger Alex Killorn and likely without injured center Brayden Point, too. Killorn had the team's third-most goals during the regular season and Point was Tampa Bay's No. 1 playoff points producer. 
The Islanders have the defense and discipline to get back into this series. The last time the Lightning had been held to as few as 21 shots on goal was March 3.
