I think MG will want a 2nd to take on RJ, or at least add a 4/5 to the 3rd.
Duke is kind of the same scenario above in terms of value, especially with retention.
I think that's a decent enough Campbell trade. Petrov doesn't add much so if it's a 1st + 3rd to dump I think MG would want XB or Broberg back as well. Also, would EDM be more interested in AB than LK? If they split up Drai and McD I would love to see AB playmaking Drai.
Overall I'd probably take these as they generally help the future.

Avs should accept imo.

I don't think Colorado will want to dump Ryjo for a 2nd if they're not getting anything in return. It's not like he's a bum, he's just not worth 4 million.

I could see Duclair going for a second as well if there's a bidding war for him come to deadline. But in a vacuum I don't see a team paying more than a third. I also wanted to keep it as grounded and "pessimistic" as possible.

I wouldn't mind Duke on the Wings. Seems like the kind of medium cost asset Yzerman would pick up at the deadline
