Does it matter who we play, honestly? Okay, if we play Boston we're out in 5 tops. If we play Montreal we might be able to push it to 6.
Chances of a 4-0 sweep are very likely.
We are porous defensively. We got to 5th because of a shortened season, luck, and offence. Those things most likely won't be in play in the opening round. It's more likely our offence drys up (as it is want to do in the playoffs) but I doubt we shore up defensively, we couldn't all season pretty much.
This was a year of good luck and fortune for us - it most likely won't be repeated next year, and likely we'll be on the outside looking in.. again.
Just enjoy the extra games, and being part of (what will most likely be) a short playoff atmosphere again.
