Perhaps the amount of chatter should have you reconsidering your assessment of the player's on-ice abilities.
Scheifele is one of the best producing centers in the league since he became our #1C. As in, the only players ahead of him are players who have had legitimate claims at best player in the league at some point during that period. Dubois scored 61 points in his best year so far. All-around includes offense.PLD is a better all-around centre than Scheifele, who's a disaster defensively. If they get him he can take the tough matchups freeing up Scheifele.
I could see something like
CLB: PLD
MTL: KK, Guhle/Caufield, and a 2nd
kind of similar to the Mike Richards trade afew years back
