I agree but if there is a great young player like a Necas or Laf being offered, we would rather take that than a quantity package. I'm skeptical on us actually getting someone like that though.
On Laf... I just can't see the Rangers doing it. The guy is a year and a half removed from a #1 OA draft pick. As I had mentioned in another post, the Rangers are young, and VERY young on D. A young team like that, with so much runway infront of them, isn't going to part with core pieces under the age of 25 for immediate help. It's those guys that are going to be relied upon to take the team to the next level.
Honestly, I think you can compare them to the 2016-17, or 2017-18 Leafs to an extent... with a really young Marner, Matthews & Nylander, but still being "led" by some more established players in Bozak, Kadri, JvR and Rielly.
Now, if the Canucks wanted to shed Miller without retention, I can certainly see the Rangers ponying up for that -- they're one of the few teams in a position to do so. 1st round pick should be on the table IMO. Vitali Kravtsov forsure. Zach Jones or Libor Hajek almost definitely.
Ultimately I think they'll probably look at their 6 core defencemen being Trouba, Fox, Lindgren, Miller, Lundkvist & Schneider.
On Necas -- obviously the Canes are a bit further ahead in their development, but I do believe they look at him as a core piece. Good teams generally don't trade core pieces. The Canes don't have a 1st round pick, and also don't have the cap space to acquire Miller (certainly not in a deal for Necas' $863k). I just can't see it.
That being said, if the Canucks do decide they want to cash out on Miller -- no question -- they're going to get a haul of assets to help them long term. The strength of that haul will likely be dictated by how much, if any they're willing to retain / look past next season towards the final year of Pettersson's deal.
If the Rangers & Leafs were the only 2 suitors (they won't be) -- I suspect the haul of assets from Toronto will be better than the haul of assets from the Rangers. The Leafs are more desperate than the Rangers are. The Toronto deal will likely require 50% retention and Nick Ritchie going the other way. The Rangers deal will almost certainly be cleaner; and allow the Canucks to try and supplement next year's roster with more than prospects.
