By having a team that pays a lot of attention to defense, wins faceoffs, blocks shots and does a great job killing penalties.
Did you watch this past season or is your PVR stuck on 2011-2012?
Instead of the PVR, check NHL.com
Here is where we ranked in the different categories:
Shots against/game - 21st (30.1)
Shots for per game - 25th (28.5)
Goals against average - 1st (2.24)
Goals/GP - 20th (2.61)
If you didn't watch the games, you would think we were getting by almost purely on goaltending. Now why this isn't completely true, it's not as far off as you're trying to make it look.
Now here is 2011-2012 (since you brought it up):
Shots against/game - 12th (29.7)
Shots for per game - 19th (28.5)
Goals against average - 8th (2.61)
Goals/GP - 19th (2.52)
Looks eerily similar with the exception of 1 stat if you ask me.
