I haven't thought this one through at all. Who says no on this?
To Utah.
Marner
Robertson
Kampf
To Toronto
Sergachev
Cooley
Hayton
2025 2nd Round Pick
They do. I doubt they have any interest in trading Sergachev after just acquiring him, and I doubt they'd be willing to give up both Cooley and Hayton in the same trade. That guts their center depth.
I think your best bet in trading with Utah would be trying to get a good player with terms, a young, cost controlled player with term and the savings in cap space associated with Marner's next deal... Something like...
To Utah
Mitch Marner ($10.9 million)
Nick Roberton (RFA)
To Toronto
Clayton Keller ($7.15 million)
Barrett Hayton ($2.65 million
Depth pick
The lineup becomes...
Domi-Matthews-Keller
Knies-Hayton-Nylander
McMann-Tavares-Jarnkrok
Holmberg-Kampf-Dewar
Grebyonkin
Essentially a classic 1 and 4 for 2 and 3 trade, where you lose the best player, but add a much needed 2C that is cost controlled, allowing Matthews to move down the lineup and a legit top line RW that isn't Marner, but can definitely fit in with Matthews and minimize the drop off.
Why would you do it if you're Utah? They're a new franchise that could build around a star player in Marner, while bringing Logan Cooley along as his sidekick. Nick Robertson also fits the age and makeup of their squad, who will be looking to contend in a couple years. Keller is a loss, but Marner is certainly an upgrade at 1 RW.
What would leave them with Cooley, Bjustad, Schmaltz, Kerfoot, McCain, Stenlund, etc as center options... I think they could afford to lose 1 more quality center if an elite caliber 1RW was coming the other way.
