they haven't won more than a round since before Covid and have two 1st round exits in a row including after the best regular season ever so the recent history isn't great either
i could be wrong but it seemed like the OP was talking about the current rendition of the bruins which organizationally has been pretty consistent since 2006, not the post chara bruins, or post rask bruins, or past bergeron/krejci bruins, or post merlot line bruins that won the cup. Just the last 15 or so years. They've been very successful over all despite not having a lot of high draft picks and seemingly having multiple facets that would make it hard to attract high end players according to discussions frequently had on this board.
we keep seeing, particularly within our own fanbase, that the bruins are going to drop off, most of us thought they would be a bubble team this year, they aren't so far. Most of us thought they would struggle a bit and fight for a wild card or 3 seed last year and they dominated the league, despite losing out to a panthers team that should be respected as well.
So like I said I could be wrong, but I think the OP's post is more about how the new organization, helmed by the jacobs, neely, sweeney, and other management that has stayed consistent at lower levels, despite having not a lot of high draft picks, high state taxes, not a terribly attractive location compared to some other cities like LA or New York or better weather, consistent roster turn over with young guys stepping up and playing above expert expectations. The athletic etc consistently gives the bruins low grades for their farm systems, people write their obituaries in one way or another - yet they continue to be successful financially, regular season, with middling success in the playoffs but still knocking on the door every year. There are quite a few fanbases that would be very happy with that level of consistency.
Bruins fans of course want a cup, but it can't be the only thing you put your hopes on because that's just setting yourself for failure given only one team out of many can win and injuries play a gigantic role in stanley cup success
