2 years of control doesn't return that much value imo
He'd be getting back 1st OA which is Shane Wright who is projected between a Tyler Seguin and John Tavares level player.
That is a premium asset in itself with 7 years of cost control at the minimum
On top of that a guy before this year was playing like a top pairing defenseman and a great goal scorer at that. Has a great contract ND great physical tools. Chychuran would be a great addition to the blue line and allow us to move Muzzin if his decline in play doesn't rebound
Hayton is the iffy piece as he's a former 5th OA but his NHL play has been poor albeit in small sample sizes on a terrible team. He could be swapped our with Guenther whose the 9th OA in last years draft.
If we dealt him now I'd ask for both Guenther and Hayton along with their 2022 1st with condition it is 1st OA if it's not we get their 2022 1st along with their 2023 1st which is only top 1 protected and chychuran
We'd get a type of package you might be looking for of we dealt him now since he has more years of control left
Could come away with
Hayton
Guenther
Chychuran
2022 1st round pick in range of 1st OA to 3rd OA
2023 1st (from 2nd overall and onwards) if the 2022 1st isn't 1st OA and Shane Wright
