Offseason

Not giving up Rosen for Chychrun, other good prospects to choose from that aren't even in are top 10. And I already get a 2nd in Johnson walks, rather sign him, which I am 80% sure happens, unless Adams makes a few D acquisitions or use him in something else. And that Edmonton trade why not just get JP instead.

Certainly not getting a 2nd from us for Johnson

They (or whatever team trades for him) will get a compensatory second round pick if Johnson doesn't sign. So, they will get a second-round pick for him one way or another. I agree though that Anaheim wouldn't do this because they will most likely be able to sign him without giving any compensation (He played for the Jr Ducks growing up). I could see a good west coast team making this deal as a flyer to see if they can sign him. The Avalanche or Golden Knights could make this trade to make Johnson say no to signing with them. If he does say no then they would get the compensatory second (which should be around 64) so they would only be moving back slightly from the pick that they trade to the Sabres.

As @greysuits mentions above, it's compensatory.

What if Arizona only accepts with Rosén included? What if they say we want Savoie or Rosén or it doesn't happen?
