12/09/2021 vs. the Nashville Predators
This one received a lot of votes, too. The Islanders finally broke the 11-game losing streak but put themselves back in a losing position shortly after.
In another game where the Islanders held the lead in the third period, they again backed themselves into a corner. Noah Dobson gave the Islanders the lead at 5:08 in the third period. Roughly seven and a half minutes later, Yakov Trenin tied things up and you could feel how deflated the Islanders were. With 11 seconds left on the board, Eeli Tolvanen beat Varlamov to give the Predators the 4-3 lead.
The Islanders were only able to muster up 21-shots in 60 minutes. It was another low-event affair in a low event game despite the score. Varlamov wasn't good in this one, allowing four goals on 29 shots for a measly .862 SV%.
It's understandable why some believe this to be the worst game of the 2021-22 season losing with 11 seconds on the clock in their own arena, but the Islanders finally started to accrue some wins after this one, even if it was only every other game whereas other devastating losses led to more uninspired efforts moving forward. Don't get it twisted, it was bad, real bad, but still not the worst.
