I do doubt that the Rangers have a serious play to make for Eichel this very second. I don't think Buffalo is at a point where they feel they need to trade him -- yet. But I think the seeds are being planted.
On the flip side, I bet the Rangers could probably take advantage, in some way, of Buffalo's growing desperation to put a team around him that can make noise, and I have to wonder if we could pry the 8th pick, or more, out of them for a player who is ultimately redundant or unnecessary to us. That list as many have speculated would include, as far as I'm concerned, Strome, Buchnevich, Andersson, and/or DeAngelo (if the price was high enough).
