Monahan and Gaudreau aren't exactly the kind of futures that would return Eichel.

They wont want Gaudreau, swap him with someone like Dube and take out the 2nd

Noway Buffalo accepts Gaudreau he'll just walk to free agency in 2022.

Calgary just isnt a good trade partner... they wouldnt be willing to give up the pieces required. And Buffalo wouldnt want 1 year of Gaudreau, and Monahan wouldnt waive his NTC.

Flames really need to make a core change.

Tkachuk is the piece that moves the needle in return for Eichel. Provided he is willing to sign a contract extension when the deal is done.

Starts with Tkachuk.

Not necessarily about the pieces in trade, but BUF who is stocked with young prospects, I cant see them wanting a package of just more young prospects.

Theres not the icetime, coaching or development space to have and develop so many guys all at once.

I believe an eichel trade will include some futures, but it would also have to contain some established (albeit youngish) players. No team could just give lge minimum youth and take on 10mil in eichel, but BUF won;t want pure cap dumps included either.

Just for illustration purposes: a Travis Koneckny, Shayne Gostisbehere, prospect bluechip dman Egor Zamula, and PHI 1st (12th overall) is probably closer, because its a mix of established guys, who are producing, making 10mil collectively, prospects and futures. (BUF has 3 center prospects they are trying to develop, throwing a Morgan Frost might be too many C prospects to develop at once. You also want some producing but youngish vets to take the production responsibility off of the kids (example: Hughes and Nico in NJ are struggling).

Take out gaudreau , add tkachuk drop the 3rd and second round picks.
