Cup Run 2

Penguins decline - Kyle Dubas is not getting rid of Jake Guentzel.
Buffalo should keep Jordan Greenway, and they don’t need Danila Klimovich.
Why would Vancouver need Denis Gurianov?

This.

Plus, Kuzmenko at this point would be considered a dump/reclamation project, so you'd get taxed on this. Yes, I know VAN fans keep arguing his potential, but if he really has that much potential you should be keeping him. That 5th would have to become a 2nd. You can remove that nobody prospect.

Sabres decline

I like the prospects over the 2nd but the deal still needs a headliner prospect.

I don't mean this as a dig to VAN fans, but they don't really have many headliner prospects. Podkolzin is probably one of their top ones. I'd prefer Hoglander if that would work. I'd really do Hoglander + 1st and call it a day. Let them ship off Kuzmenko to another team to make space.
