It's clearly something they value, but I'm not ready to lump it in with the character buzzword from the Bergevin years just yet given we're not seeing Prust/Shaw type of stuff from them and Slafkovsky was very much a talent & upside pick even if you disagreed with it. The way I see it is that to win in the NHL, you need a market efficiency somewhere, and it needs to materialize in 2-3 guys on your roster that piss off other team's fans because it's bullshit you got X guy for Y price/pick. For Tampa that was HOFers in the 2nd/3rd round. For Vegas, it was acquiring Mark Stone and Jack Eichel for Jack Shit. You need bullshit like that on your roster to win in a hard cap league with a negative feedback loop baked in to the draft format.
I think what they're doing here is trying to get that roster bullshit by going all-in on their development system, and "culture". They clearly think St. Louis is a pretty unique/special development coach, and they're trying to give him a bunch of athletic, skilled, and hard-working canvases to work with and build a tenacious, fast, and skilled team with depth and some nastiness. I think they believe in Nicholas and St. Louis to get some bullshit development out of a guy or two, and if they can't pull that off, the trade market should be pretty damn efficient for us if we can build every trade package around a big toolsy defence prospect, a surplus middle six winger, and magic beans.
I would just be very wary about drawing major overarching conclusions about "culture" and going into Bergevin talk from this draft and the Michkov decision specifically. It's a really unique situation, and I think it's a stretch to just call it "passing on skill" in a vacuum. A week ago they gave Cole Caufield 8 years and over 60 million, traded for Newhook, and a year ago traded a gritty fan favourite with character in spades for a then-underwhelming Dach (and added Matheson). They like to make bold trades for skilled players, and maybe it's copium, but I'm confident they'll be similarly aggressive at trading for star talent once we're out of the Dach/Newhook trade phase of the rebuild.
