I guess. Maybe they get Kane, Necas,Zegras, etc. ,but right now they just lost depth.
We van of course speculate. But remember this, the Sabres don't really lack totally in scoring, they've been pushed around on the ice, bo on ice leadership, no response when they were being out played.
Yes, I agree, they'll need to add a top 6 or 2 lifted element, but their bottom 6 needs to be seriously addressed. Their defense is young, but maturing, with a couple of good pieces. Their goaltending is now coming of age, UPL and Levi have proven top tier.
They need muscle with speed and skill and the maturity to guide the young now coming of age. They need a 3rd piece to the Tage/Tuch line, and they need face off improvement up and down the center ranks. See what is in FA, what is trade viable, and deduce their moves from there. Chances are, you won't be far off the mark once incorporating this info
