I'm trying to understand what exactly you are looking for-
You want Zacha straight up but McLeod might be an alternative-
So McLeod for KS straight up? Where's the overpayment? And who does not take that from Jerseys side? (edit: STL could have worked that deal at the draft no?)
Then on the overpayment with the qty as you call it, you say not enough (talent I guess)
Lastly run through the teams you have listed (prob should include Isles to, KS lived about 20 miles from Nassau) and give us a list of the player(s) you would accept as return. Except for the NYRs (who overpay for everything and would absolutely do so here!) The lsit will be somewhat similar.
I'm assuming there would be other pieces involved, probably on both sides. I'm only specifying the major pieces.
The Blues need a quality, NHL-ready, cost-controlled center with top-6 potential, or a fast winger with good hands, a little toughness, and a nose for the net. Those don't grow on trees, but neither do defensemen like Kevin Shattenkirk. Zacha is what the Blues are looking for, but it's understandable why NJ might balk at moving him. McLeod isn't NHL-ready, but he's talented enough to draw the Blues' interest; so, it's conceivable that NJ might be able to put together a package built around McLeod that the Blues would bite on.
Apart from Zacha and McLeod, here are some other players I'd be interested in, as
part of a package in a deal for Shattenkirk +.
I'm making no claim regarding the relative value of any of these players, nor am I commenting on their availability, or the feasibility of any such deal:
-Galchenyuk and McCarron (MTL)
-Kreider and Tambellini (NYR)
-Miller, Hayes and Tambellini (NYR)
-Larkin or Nyquist + Holmstrom (DET)
