Johnson would probably cost a 5th un-retained and third with retention.

Probably not much as they really aren't better than what the Leafs already have.
But think Sunquist would be the best addition and a one Dman

Lyubushkin will cost you a 2024 3rd

Don’t see why the Blues would trade Sundqvist for what they’d get for him.

Presumably, the only way Sunny leaves is if he asks for a trade, which seems quite unlikely. And he probably just returns to STL as a UFA if he does get dealt.

That said, he'd normally be worth like a 4th. The thing is, if he was available, half the contenders would jump in for him. So it would probably end up costing a 3rd or so.

For E.Johnson, we’d want a mid round pick most likely

Adams seems to like "Future Considerations"

Probably a 1st for each one

It would be very cool to get a third for Edmundson with 50% retention. I’d personally take a fourth though

stecher is out at least 6 weeks so prolly not much
