It all comes down to goaltending. We've seen both of our goalies getting cold at the same time on a few occasions...if that happens we're f***ed...otherwise round 1 shouldn't be an issue regardless of the opponent.
I pretty much only fear the Stars and Blues in the west.
Even with shaky goaltending... A healthy Avs team was putting like 4.5 goals a game this year(Small sample size obviously).
It would be much harder to do, but we have the offense to overcome a bad goaltending performance in that first round against most teams we would potentially face.
I'd say IMO only Vegas, Dallas, and the Blues would we be truly f***ed in a series if we got sub .900 goaltending.
