Nope.

Mayfield's a 3rd pairing guy, you're playing him too far up the ladder. No contender does that.
Keith is one of the Oilers better defensemen, you've scratched him for a very raw rookie. No contender does that.

the short answer is no

I’ll give you Eakin for a bag of pucks

I see what you are doing with the Buffalo trade.
I presume you want Eakin to PK and win FO.
I do not know why Sabre ACGM's do not understand how valuable those qualities are to HC and GM.
IMO you would be better to get Hagg instead of Pysyk.
Not the Pysyk is bad just Hagg is LHD, hits more, blocks more shots and actually spends more TOI PK than Pysyk.
If I were the Buffalo GM, I would make this trade or the Hagg substitution.
