All due respect, I don't know if I agree with your breakdown here.
Is there really any evidence that Burakovsky was picked because he'd be a good fit in the locker room? He was continually in the doghouse in Washington. Nichushkin had a downright toxic reputation both in the NHL and the KHL, the Avs decided to take a flyer on both, and we should be glad they did. Both were most assuredly analytics-informed decisions. I'm not so sure intangibles were a factor, however.
Conversely, I don't think Dubas just ignored intangibles and went only with what the numbers told him. If he did, he never would've signed John Tavares. He's an elite talent but also in his late twenties--that's a decision based on the leadership qualities he brings as much as it is his talent.
And I'll just reiterate--I don't think it's really accurate to call Chayka an analytics "whiz kid" because nothing he did in Arizona remotely resembled what an analytics-driven front office would do. Call Dubas that if you want, I guess, but he also proved this last offseason that he values "old school grit" a lot more than any of us, me included, ever thought. Really, the "poster children" of the analytics movement appear to be Tampa, Detroit, and Colorado.
I'd like to break down where I think Dubas failed when I have the time. Most of it has to do with goaltending and some key prospects that he just plain bet way too much on. Also, in hindsight, I think the Tavares signing was a huge mistake, despite the fact that he's played quite well for the Leafs. But I'll wait to do that when I have more time.
All due respect to you as well, but is there any less evidence for what I'm saying about Burakovsky than what you've been saying? These are all informed guesses we're making.
Any GM and pro scout worth their salt is gonna do their due diligence on potential new additions. They're gonna talk to agents, they're gonna talk to former teammates, former front office staff, and especially former trainers who know these guys the best, to get an idea of what type of person they are.
Otherwise you're just looking at numbers instead of asking yourself how the situation they were in led to those numbers, and if the situation you're trying to bring them into with your team will be different.
I think it's a pretty safe bet they correctly identified that the Avs team, that happens to have a Swedish captain, might be a good fit in the locker room for a skilled guy like Burakovsky who as opposed to other skill guys that another GM might bring in, doesn't really appear to be that high maintenance or a prima donna.
I think a smart GM who knows how personalities mesh together in the locker room and on the ice, might also have seen that the more introverted Burakovsky might actually become buds and get along well with the extrovert Kadri. Which we've heard is true, as all three of Naz, Saad, and Burky have talked about their success as a line partially stemming from being close off the ice as well.
All of this applies to Nuke as well. If he were just a former 1st round pick that struggled in Dallas, I doubt they'd have brought him in, but they identified that he'd be a good fit in the locker room. A guy the whole team would love, and would root for and help him to get closer to his potential. And from what I recall, despite his troubles, his teammates in Dallas all spoke pretty highly of him as a person. And I'm sure the Avs knew this and it played a big part in bringing him in.
I also think you're giving too much credit to how Dubas and Chayka slowly learned to value more than just the analytics. Them making decisions in their most recent years that may or may not have gone against the analytics (I'm taking your word on this because I'm not as familiar) isn't a sign that they valued this all along, it's a sign that they were too slow to realize it's importance, and probably hadn't fully addressed it.
Sakic and Colorado on the other hand were the opposite, as they were slow to realize the importance of analytics. They slowly began placing more importance on this around Roy's second year, and then started building up their analytics department.
They didn't have a full time analytics guy until they made Parnas full time in 2016, the summer before Bednar's first year. Then they brought in Dawson Sprigings in the 2017 off season. In the 2020 off season they brought in another guy in David Wood.
So over the course of the last 5 years they've gone from only using part time guys, to having a full time guy with a decent staff around him.
Sakic was a guy who knew what it takes to build a "team" but he had to learn to appreciate the value of analytics in this new NHL era.
Dubas is a young guy who doesn't have anywhere near the kind of experience Sakic has in the former department, but was well versed in analytics. So he's slowly been learning on the job what it takes to build a "team" of grown men with all the personalty quirks, egos, and character traits that involves.
It's just like with building a team in general. Some teams like the old Avs and current Leafs are going to start out with good offensive talent, and need to learn how to play well defensively before they can compete. Other teams are going to start out more defensive like LA and St Louis did, and they have to add more game breaking talent to be able to compete.
Then there's teams like Jarmo in Columbus who just go all in keeping a defensive coach past his shelf life, and with defensive/two way players at the expense of talent, both in the draft, and most of their roster decisions, and they end up a perennial bubble team at best.
That ended up being a much longer post than I originally planned, sorry.
