Just thought I'd throw up a fun list of the players who created the most offensive chances the last 2 playoffs. I dont think you are giving the insane goaltending streaks both Columbus and Montreal went on enough credit.

Note that almost every player here failed to advance due to a goaltending difference between the teams as well as, certainly in the Leafs case, a lack of finish. Just go and rewatch the series with the Habs. Posts, near misses and big saves against all day.
This is all useless in playoffs if you have no results.
This is more useful for regular season. The sample is big enough (82) that eventually the advanced stats are consistent with the standings.
Playoffs you just need to win 4 games first.
So here's a very simple model. Leafs playoff advanced stats suggest that in 50 games they'll probably win a minimum of 30. Habs advanced stats suggest they won't be so lucky. In 50 games they'll probably win a minimum of 20. Again very simplified example.
So Leafs have 30 wins as currency , Habs have 20. Each team has enough currency to produce 4 wins. Leafs to this point don't have what it takes to get those 4 wins first and that's the stuff the advanced stats can't measure.
Champions will fight and get those 4 wins even if they're the under dog. It doesn't matter that they probably wouldn't sustain it over a whole season. It's the playoffs you only need to break things down into 7 game segments and get your 4 wins first.
There's no math on the planet that can measure "clutch " . You either have it or you don't.
What I do like about the advanced stats is they suggest if Leafs can get past the first round hurdle, the run will be deep because as the sample of games increase the advanced stats do prevail.
I think Leafs will put it together soon (marner thread so I'll single out Marner as not being clutch), but so far they lack what it takes to be champions. Takes more than skill.
