Not a huge Nash fan at this point, but the Rangers will get a solid return if they move him.
Personally, I don't see a return to 35-40 goals.
I don't think 25 is unreasonable, maybe even 30 IF he's in the right situation (aka Kessel in Pittsburgh).
But I also see a player who over the past 18 months has clearly shown the signs of a player who has begun the downside of his peak production and whose injuries have resulted in a style change that's still impactful at times, but not quite as impactful as it once was.
