These are spectacularly light offers, no?

Martinez plays the wrong side, Buffalo needs a right handed defender more. DeMelo fits a lot better, but they don’t really need to pay for Hellebuyck. Foegele doesn’t work for Buffalo either. I think Buffalo looks to the free agent market for the defender they need instead of overpaying in a trade, unless they can’t get the guys they want.

Looks interesting

Not enough going to Winnipeg.

Cant see Winnipeg trade. Jets would want more, Sabres are not necessary willing to extend Helleybuck.

I don't see Edmonton paying to downgrade to a player type they haven't been going for. If you look all their acquisitions have been big, fast and physical. Built for playoff hockey.
