I see this repeated a lot, and it's just an exceptional false equivalency to say that because it was a bad idea for the worst management in NHL history to try building around two 35 y/o players in steep decline that it's a bad idea for better management to try building around one of the better young cores in the NHL.
The other one is 'they've been doing the same thing for 10 years!' and no they haven't. We tried keeping an old dead core alive for several years, accidentally accumulated some high picks in the process, and then for 1 offseason (2019) kind of built around those young players by adding Miller (good) and Myers (bad) and it actually worked fairly well for one year. Then absolutely no more building around the young core happened beecause they were bit in the ass by all the dumb deals they signed 2015-2018 and spent the 2020 offseason being gutted and the 2021 offseason converting those bad contracts into OEL in the worst deal in the NHL in the last decade.
Very little building around this core has actually happened. It's mostly just been dealing with Jim Benning's mess while the core rots on the vine.
I can't speak to what post, specifically, you've seen with regards to re-tooling around the twins and re-tooling around Pettersson and Hughes, but it's only a false equivalency if the two players are used as the basis for the rebuild/re-tool decision. Nobody is comparing the two sets as equivalent. They are used as examples of the poor rationale GMs use to decide a course of action.
It's actually the lack of understanding about how difficult it will be to re-tool around those key players that's the crux of the issue, not those two players themselves.
I've seen you post a few more points that I wish to address as well:
Timing: The right time to re-tool is determined by, first and foremost, the likelihood of its success. If the re-tool has a 10% chance of being successful, it's horrendous management to try and force it and bank on the exception to the rule. What you're advocating works against probability, not for it.
The 2 year window: What's the template for this 2 year turn around? I remember you mentioning Seattle, which was not a re-tool. Maybe if we ground the discussion in an example, we can better gauge the likelihood from there.
On Picks: You've stated that collecting picks for their own sake is video game based GMing. Or that it's draft pick FOMO. You can't pick players unless you have the picks. And good players on ELCs are the most valuable commodity in the league so... Cost controlled assets are necessary to create a valuable roster.
We disagree on rebuild/re-tool, fine, but to categorize the need to rebuild as "pick FOMO" is beneath you. We can't on the one hand say that to master the cap, we need valuable contracts, and then say people want picks for their own sake. No, it is instead for the potential value the good young player adds to the roster.
