Yeah, but a few things happened along the way
- Pasternak decided to go supernova and look like a top 5 player in the league this season instead of just the excellent top 5 RW he was previously
- Krejci came back to the league looking every bit a mid tier #2C, didn't miss a beat
- Zacha broke out (by Zacha standards) into more of a top 6 winger than a 3rd line winger. Debrusk scored at a 35 goal pace.
- Trent Frederic became a bit of a bottom 6 problem
So yeah, a bunch of things went right for Boston this year but it's hard to know what are trends (Zacha, Debrusk,& Frederic are all young enough that actual improvement can't be ruled out) and what was fluke/heaters/etc. Also, they went apeshit after having a great trade deadline.
I don't think anyone is really a 135+ point team all the time. That's a level of pure dominance that is probably impossible in the cap era without an outsized dose of OT/SO luck.
But regardless what their final point total was, just looking at the earned nerdies and the roster quality, they're a fucking problem.
