For Buffalo, I feel like their version of a 1st (or two) and a 2nd is going to be better than any team in on trade talks based on expected draft position. Even if Buffalo makes the playoffs, they're out quickly against Bos, Car, or NJ. Based on that I can't see KA giving up the reported ask without removing a piece or watering down the 3-piece package. Also, Buffalo has all the cap space so there's no need for ARZ to retain salary. I would go up to...
2023 1st and Rosen, or...
2023 1st, one of the 2nds, and a lesser prospect (Poltapov, Komarov, etc)
Anything like the 2023 1st and Kulich/Savoie, or including Samuelsson is either over the edge or damaging to the room. I don't see Armstrong pulling back on the demand though, so I expect this trade scenario (like almost any involving Buffalo) to ultimately be nothing more than smoke.
