Tbf, I think it helps them more than us, as I think it's going to flatten the gap between the teams a litte.
You're right about the rest of it though. Not that people aren't right about the potential banana skins but that's what they are.
It really depends. Great coaching can be a great equalizer, I agree. However, we have great coaching too and they have many more flaws to exploit. Despite being analytic darlings (meaning, they probably have a good system), they were still bottom-dwellers (which means they have shit talent). Maybe they could surprise us in game 1 with a weird game plan, but that advantage would last a period and even then, they do not have the talent to put 3 on us early... unless Murray shits the bed completely. They can neuter us for a while, but I do not see them having enough offense to capitalize on that... unless Murray shits the bed completely. It took them insane luck, Fleury being poor in the last two games, Subban slicing Staal's achilles AND Halak standing on his head to beat us in 7 games in 2010... and THIS Pens team is likely better/deeper + THIS Habs team is a lot worse (Gomez, Cammalleri and Gionta were legit at that time, Markov was a great D, they had 2 good goalies).
Julien is a match-up guy. He'll want Danault/Weber against Crosby. Then... what? Suzuki/Petry against Geno? Suzuki is good and responsible, but he is also very young. Petry is not a defensive defenseman at all. If I am Sully, I deploy Jake/Geno/Rust with Marino behind them against Suzuki/Petry, hell, maybe I even go Letang/Dumo with Geno at times to accentuate that advantage. We should OWN that match up. Danault/Weber can play Sid/Letang to a draw and that would be fine for us. I do think Sid (Sheary and Zucker) and Letang (Dumoulin) would win that match up though. But, honestly, Danault/Gallagher scare me more than Tatar or Drouin or Domi (if he even plays). They can win on both sides of the ice. One of Tatar or Drouin will play with them.
Their fourth line is full of bad players, we probably have the best fourth line (according to analytics) in the league. That line can also be used against Danault's unit at "home" so we can give Sid a few key shifts against shit opposition.
Their special teams have been atrocious all year (and that's why they are analytic darlings, their 5v5 is not that bad). With the talent we have on our PP, we need to exploit that. Also means we can play physical without fear as their PP is crap.
We have speed on every line and can push the pace wave after wave after wave. We will have the puck more, we will shoot more and we have match-ups advantages everywhere. I mean, Carey Price would really have to steal games by himself for them to beat us.
The Habs cannot win 5-4 against us, they need to shut it down and hope to win 2-1 every game. In a short series, it could work, sure. But the talent gap is soooooooooo huge.
I mean, I fail to see what advantage Julien could gain on Sully, even with one month of preparation.
Still, as I said, it is the NHL, so we could be swept even while dominating each and every game. It has happened before and could happen now. Still would be a huge upset and cause for concern. On paper, this Pens team SHOULD be favored against pretty much everybody but Boston and Tampa. Does not guarantee results, but let's not act as if the Habs are a tough match up. They aren't.
