The Isles lost in the Conference finals last season to the eventual Cup winner, playing the exact same style. Their style is anything but negative in the playoffs.
This season might be tougher for them without Lee and their window might be closing, though.
They also had 4 and a half months between the regular season and the playoffs. Of course, so did everyone else, but last season is mimicking this season. Their final games of the 19-20 season were pretty much similar to these games now. 12-14-6 was their record after Christmas last year. That begins at game 36 of last season. I could have gone before that day and there would be more losses, but everyone gets to reset after the holiday, so it seems like a decent time to begin counting.
If we do the same for them this season, from game 36 on, 7-6-1. It's better than last season, but they also ended last regular season on a crazy losing streak. So much that it was thought that the Rangers could catch them and were really close to doing so. If they finish the season, it probably happens. They run out of steam. Playing their brand of hockey over a condensed schedule is going to cause that.
There is a soft landing after their games against the Rangers, but as we just saw, the Sabres actually play now and the Devils just snapped a long losing streak. Nothing to play for and if somehow the Rangers come through and win these two games, the Islanders will have all the pressure on them. Last game vs Boston could be for either of their playoff lives. We'd also still be asking the Rangers to almost run the table against Washington and Boston, and if they do, they'd be finishing the season on a 9 game win streak.
