You can even look at the Habs of this season. They played way better than we expected because they finally had a team identity of speed. Everyone thought we’d be battling for Hughes.
When the Habs got their asses handed to them by Lucic, they went and drafted guys like McCarron and Tinordi. That set the team back big time. The NHL was different then but the reason the Bruins won the Cup in 2011 was not because they were huge, it’s because Thomas played like a god and they went and added key depth players like Chris Kelly and Rich Peverley.
Even when the Kings won the Cup twice, everyone thought “well they are big”. They don’t win those Cups without two key deadline acquisitions - Jeff Carter the first time, Marian Gaborik the second time. Fast, skilled players. Also Quick had a .930 SV%
Here's the ingredients to a cup win:
Luck - you need lots of this, be it teams that you don't match up well against getting eliminated before playing you, or getting a good draw of teams you can beat. Plus not having major injuries.
Depth - If you have injuries, which you will, you need good cheap depth that can come up and play over their heads long enough to do it.
Goaltending - No, this doesn't mean you need Carey Price, but you need a guy at the very minimum making key saves and not giving up bad goals in key moments (see Patrick Lalime)
Talent - You need this and lots of it.
Coaching - A guy who can get the most out of his teams and players.
Strong special teams - You need a strong PP or a strong PK, ideally both.
Put the spin on it that you want.. LA was a talented team, Chicago was a talented team, Pittsburgh and Washington are talented teams.. the Bruins and Blues are talented teams.. neither of them are where they are without Pastrnak, Marchand, McAvoy, Shwartz, Tarasenko et. al.
