Not sure how you trade a 1st and a 3rd for a d-man, and throw away the potential that Sundin has, IMO.

I agree. While I like the lineup, Sandin looks to me like he’s gonna be a big piece of this blue line for years to come.
Trading Muzzin is more of a priority than Holl. I’d keep Holl for all the reasons you listed in your description.
Muzzin trade is gonna be very difficult and return doesn’t matter as it frees up enough money for sandin and Knies (when knies joins the team for playoff run). And even a little left over for salary retention in a Muzzin deal if necessary.

I think you think demelo is a lot better than he actually is. The difference between him and holl isnt near worth that

Muzzin would have to waive so a trade would be unlikely & everytime i trade him i get told off cause of his NTC

Unless it’s an actual nhl gm telling you, I’d say anything is possible.
