It's essentially Kuz, Alexeyev, McMichael, and the 1st+Jenson (for cap) and Clark as compensation for Jenson.
Reason for Kuznetsov: Cap move for Washington, can be flipped later by Buffalo
Reason for McMichael: Sabres need quality centers in their system (I guess MacInnis and Hayden just can't cut it) and this is especially true for when they trade Eichel.
-(To put this into perspective the Sabres depth in their system is Ruotsalainen, Malone, Hayden, MacInnis, Pekar, Oglevie, Kozak, Konecny, and Constantini)
McMichael fits the bill of a quality center, ready to make the jump.
Reason for Alexeyev: Future Top 4 D-man; NHL Ready
Reason for Jenson: Purely cap
Reason for Clark: Sabres don't want Jenson, Caps can't keep him. Caps trade a position that they are very solidified at (in RW)
I know it may seem like a lot and that I overvalued Eichel, and that may be true, however, I sincerely believe that upon his return (whenever that may be) Washington would be getting a player that can help them make this final push for a cup, and even pushes for ones post-Ov and Backstrom.
If you disagree with me, tell me cause I'm not a Washington expert and am completely aware of potential biases that I may have had while making this trade. Not to mention, that I may not know something about a Washington player, that would make Washington set on not trading him.
P.S. BUF may have have to take cap back in STL deal as well
I think for the most part theyre pretty fair. You did not get too much back for eichel its actually spot on imo.
As for the blues trade, if youre retaining that much i think you could get some more.
But overall a very good ACGM.
Side note - i dont see STL being the right destination for kuzy. They are stacked at F already and after probably moving on from tarasenko by the TDL dont want to have another locker room problem.
