The thing is, there's no team in the east that matches up well against us except the Flyers for some reason. And the Flyers team that used to convincingly beat us in the playoffs is long gone, while the Habs, despite their playoff run, have been much better since 2010 except for the Cunneyworth "era". The Bruins and the Penguins are allegedly the "contenders" in the East and we have a habit of outplaying both of them.
We definitely struggle against the big puck possession teams in the west - the Kings and Blues especially. The sample sizes are small but the results are pretty ugly even when we managed to grind out a few results.
But top say we are not good because we struggle against the Flyers is an extremely high standard. We aren't elite, we have a few serious problems keeping us from being elite, but this isn't the NBA where a .500 team can be the 4th seed. This team does have the talent to go on a good run with a solid coaching and luck, which is why the talks to blow it up after every slump make my head hurt.
