I think Utah would take that deal and run. Hayton is somewhere between a 3rd and 4th line player, often injured, mediocre offensively, and easily replaceable around the league. Only because of his potential and draft pedigree is he even still in the organization. And uh, that isn't looking so great.
I think this deal is probably better than most we've seen but I don't think Samuelsson has potential to be a #1 or #2D. I think he projects as a #4D who is potentially shunted to the bottom pairing if there's a better D available. I also don't think Komarov is an amazing piece, he clearly has potential but he probably has to fix some stuff too and his skating may not make him any more than a bottom pairing defenseman. There's a decent chance he's better than that of course, but I wouldn't say it's likely.
All that to say while I think it would be great for Utah to get both Sammy and Jokiharju, and I think they would be the ideal bottom pair on almost any team in the league, I don't see Sammy edging out Moser or Durzi (who are both pretty much ideal 2nd pairing d-men) on Utah's left side, and what Utah really need is a top pairing (or at least closer to it than Moser and Durzi are right now) d-man or two and ideally at the very least a RHD to push Durzi down. Simashev also projects as very similar to Samuelsson and is also a LHD so if Utah isn't going to stop the rebuild short, I doubt they have any interest in this.
Especially because Crouse is just kind of untouchable in general. We've always heard lots of rumours of teams coveting him but there hasn't been a single hint from staff at any point that they're exploring trading him.
Would Buffalo be interested in one of our centers (Hayton, possibly Kerfoot, Schmaltz, Bjugstad) and a combination of picks for Sammy + Jokiharju? I think that would be more the deal GMBA would be interested in making.
