Depends on what else they're willing to give up. Like I said, take Byfield and Clarke off the table and see what else they've got. We could be better off getting multiple pieces in return.
I'd be open to something around Petersen, Durzi+ for example. If they think Clarke can make the jump next season maybe there's something there. Petersen would give us a stopgap, Durzi would give us a top 4D. Say we get a 2nd too, I'm just spitballing here.
Losing Durzi would suck for them but it's gotta hurt somewhere. Clarke projects as their Doughty replacement, Byfield is likely their best chance at getting someone to eventually fill that Kopitar void. Would they give up a top 4D+ for a younger starting tender with term attached? Maybe.
I'm not convinced we're looking to move Demko though so it's really neither here nor there.
