Here is a better question, for those that don't want Robertson (valid reasons)
Is there a price in which you would take him?
If the Stars lost their mind and they just wanted Schneider + Berard, how about then
I want this team to spend less money on skill wingers. So the issue isn't as much cost of acquisition as it is the percent of the cap hit we'd be spending on the position.
My hope is that within 12 months, Kreider and Panarin are gone. Ideally both by trade to maximize the return, though trading Panarin may prove impossible until it's just his early UFA negotiating rights.
Mika also has a NMC and will be nearly impossible to trade, but if he ever agreed to waive, I'd do the same for him. I can justify his continued time here because he can fill in at C for injury so he serves a dual purpose, but the fact that he absolutely has to be on the top PP to be useful sucks.
My preference would be to add a star LD and star center. Star C- Miller-Trocheck becomes a top 3 center trio in the league, whereas right now we are middle of the pack. Adding a top level 1LD allows us to have two solid pairings. Duhmetre suggested something like McDonagh-Fox, Gavrikov-Borgen, Miller-Schneider which would be a top tier D unit. No way we play Miller on the third pairing, but that gives a good perspective on how much better the roster looks when we add two honest to goodness top 4 D to the mix. Tampa Bay's ability to have Hedman or prime McDonagh out there for 48 minutes a game was a big reason for their dynasty.
NYR's young organizational strength is wingers (Perreault, Othmann, Berard, Cuylle, etc) so those guys can grow into their roles on the wing to complement the good centers.
So for Robertson, I'd only really be interested if it meant we had not only committed to moving Kreider, but also had a deal lined up for Panarin or Zib somehow. And given the asset cost, I'd much rather we go all in on a defenseman or pivot.
The dream imaginary NYR lineup is
Lafreniere-Star Center-Perreault
Cuylle-Miller-Zibanejad
Othmann-Trocheck-Berard
Edstrom-Carrick-Rempe
Pars/Brod
Miller/Trade top LD-Fox
Top LD -Borgen
Vaak-Schneider
With Soucy, Panarin, Kreider out and a top center and top LD in. More realistically, since moving Panarin is likely impossible, replace Perreault with Panarin (Flip sides with Laf) and use the unlimited power of your imagination to figure out how we fit a top center and top LD with that cap space and the assets we have. (Which we can't, which is why I'm warming to asking Bread to waive, esp given his shitty conduct and playoff performances)
