That argument doesn't work against Vancouver. They have been one of the top teams since the coaching change, they're playing their best hockey right now, and that was a playoff atmosphere.
That game wasn't anything close to New Jersey.
This isn't directed at you, but it's odd how many fans adopt the team propaganda about being built for the playoffs. They're not. A run of any kind in the playoffs would be a truly stunning, Cinderalla-type situation. Teams win in the playoffs because of depth, 5 on 5 scoring, and goaltending. Dallas wins in the regular season because of 1 line, the PP (previously), or a skills competition (3-on-3/shootout). 1 of those things doesn't even come into play, special teams have a dramatically smaller impact in the post-season, and shutting down a single line in the post-season is much easier in a series.
I'll turn full fanboy when the playoffs start simply hoping to see guys like Heiskanen, Robertson, and Oettinger get valuable experience, but Gaglardi, Nill, and Bowness' lines about being built for the playoffs are pure propaganda. They're trying to distract from uneven play in the regular season. It's an excuse 100%. Hey fans ... ignore the erratic, maddening play this regular season because we got you once the playoffs start.
They're not even defending at an elite level anymore. There's not a single area of the team you can point to that has been consistent and a key area that is typically required for playoff success. At least in the past, you could sort of hang your hat on being an elite defensive team.
As I said, I'm completely ready for irrational fandom when the playoffs start, but nothing this team has done this season suggests they're remotely prepared for the playoffs.
