Chych had a higher CF% and xGF%, but Ghost did have a higher P/60. I'm not sure what you mean by every category, but Chych was definitely better possession wise.
Durzi is not slightly better offensive wise, Durzi had a .56 ES P/60 last season while Chych had a 1.05. This year Durzi has a 1.18, while Chych has a 1.58. You mention career PPG, but fail to account for the fact that they are nearly the same age, but Chych was playing in the NHL at 18 years old. Since Chych was 22 he put up seasons of .73, .45 and .81 PPG. Since Durzi was 22 he put up seasons of .42 and .56.
Chychrun is not the same as Durzi, I mean you say it is easy to have good relative numbers since Chychrun plays on such a shit team. Did you know that Durzi has a higher CA/60 and a high CF/60 this season? That's not relative, those are just rate numbers, if the Kings are so much better than the Yotes(which, obviously they are), then you would naturally expect Durzi to be far outstripping Chych in those, but he is not.
I just can't believe we are still trying to argue that Durzi is the same as Chych at this point. Injuries, I get that argument, cost to acquire, I get that one too. Durzi is just as good? That's wild to me.
Do you have any stats to back up his deployment being the only reason he is near the top of the league among defensemen by nearly every category? If it was so easy to "juice" numbers, wouldn't every team not contending be doing it?
I was more looking at indie stats, not so much possession. It wouldn't surprise me that Chychrun had better Corsi at all. Gost had higher goals/60, assists/60, points/60, he was a better offensive player against better competition.
I do think Durzi is a tad better offensively. If you look at their points as a whole not only does he have a higher ppg, but his points/60 is substantially higher. Chychrun is an impressive 1.29. Durzi is a 1.44, which is obviously really high. I think Chychrun's shot is one of the best in the league, but I think Durzi's overall offensive acumen and IQ are higher. This isn't to say that Chychrun isn't effective, he's really good. Durzi also hasn't had the benefit of being in the NHL as long. Note that I don't think that Durzi is just as good as Chychrun, just offensively. His defense still is on the suck spectrum.
My biggest concern with Chychrun is this:
His GF% is stellar, but he faces some of the worst competition on the team. It's a small sample, but it's fair I think.
This is last year:
His GF% dropped like a stone when he faced harder competition. There are lots of factors, but that's a concern.
Here are the Kings, for reference since we see them more:
Durzi's not as high of course, but he's facing 2nd pairing competition. Man, Edler and Walker are bad...
If you go back with Chychrun's numbers they are kind of in the middle, some good (esp. 19-20), some bad - but he undoubtedly played his best when stapled next to Goligoski on the 2nd pairing. I guess Roy is the closest thing we have to that, but could he do that for Chychrun? He's not near Alex's level.
Doughty-Anderson isn't being split up, it works too well, and Chychrun is best on the 2nd line anyways. He'd probably be with Roy, with Durzi sliding down to play with Edler. Bjornfot and Durzi have been awful together, I'd rather not see that one revisited. You can certainly argue that Chychrun is better offensively than Durzi, but there certainly isn't a big gap between them. The defensive gap is going to be there, but is that gap enough to justify the cost and risk? I don't see that at all. I don't completely hate the idea of acquiring Chychrun, he's an overall upgrade on Durzi, who would probably end up being moved, but the cost will be ridiculous.
My preferences for LD targets that I think will benefit the team most are:
McCabe
.

Provorov
Chychrun/Gavrikov
