If they bring the game they've brought this far to the playoffs it will be a short series regardless of how good the matchup looks on paper.
This, 100%. The Islanders have played much better than the Bruins so far. Yes they've had to being in an elimination situation, and I'm not sure the Panthers really turned up, but they're definitely rolling along nicely. No doubt Boston matches up well against them, but that won't mean anything if we don't significantly improve our game.
But it can be done. Things change quickly in playoff land. Last year the Islanders swept the Pens and looked amazing in the 1st round, only to roll over tamely to the Canes in the next. For all their issues, we know what the Bruins are capable of when they click. With the Islanders you feel the Bs will at least have a chance to keep things tight and grind out a result even if their offense is still sluggish in coming fully up to speed.
