Pretty small contracts for Dube and Valimaki

Tkachuk+

Monahan, good top line center certainly not in the Eichel category
Bennett, his production has really dropped off the last two years, IMO does not add any value to the trade as Buffalo has many bottom 6 forwards.
Kylington, LHD Buffalo could use him for depth purposes.
Zary, IMO a solid piece of this transaction. He could be in the NHL in two years
Parsons, decent GK prospect. Buffalo has a couple of good ones so this does not add much to the trade.
Giordano, Solid veteran LHD still producing with only 2 years remaining on his contract.
2021 1st round pick (CGY)
2023 1st round pick (CGY)

I put in bold the key pieces.
While Monahan will never make any one forget about Jack he is solid.
Giordano may be just the defenseman who could help our young blueliners develop.
Three good pieces for the future Zary, 2021 1st round pick (CGY) and 2023 1st round pick (CGY)
While I am not inclined to trade an all star center, the Sabres are spinning their wheels the last five years. I would bite the bullet and make this trade.

What about: Eichel and Miller for Monahan, Hanifin, 2021 and 2022 first round picks?
