To my mind Nylander is significantly more valuable. He is bigger, faster, younger, and just as skilled as Drouin. It's hard to say how good he is, however, and even harder to say how good he will end up being. Ehlers is closest comp, for me. A really, really exciting player with speed and offensive flair, but not a player that you build a team around. In other words, I wouldn't expect him to be be much more effective than a Zucker presently is...which is not a bad thing, I'd love another Zucker...but you only want to pay so much for one. The intriguing thing about Nylander is if he ends up being similar to Granlund, but with bigger and faster.
I just don't know if the guy has the heart and grit that a player like Granlund, or Spurgeon, has. To me a guy like Drouin, for whatever reason just doesn't have "it". Would be a drag to pay a ton for a Nylander, both in trade and in signing him long term, then find out he is another Drouin.
Panarin is a much higher end player, but I doubt he would be much more than a rental, and the Wild would have to keep that in mind when they make an offer. If he agrees to sign a new contract with the Wild before the trade is made....well that's a whole different thing.
If MN does trade Spurgeon for Nylander, then it will make us a worse team for now, and probably the next few years. Will also cost us in cap, and might be the difference in us re-signing a guy like Staaal....not the end of the world, but let's not kid ourselves that he will be next to impossible to replace. The reason we do that deal is if Nylander improves, and becomes a 75 pt. C, rather than a 60 pt. winger.
It's a gamble.
I don't want Drouin on this team, at all.
