No I am meaning Alexeyev more than any of the players you have offered. Let's face it Eller isn't worth anything. You haven't really given enough for Parayko, it's actually kind of worse.
I think if you could move Bozak you'd love Eller, but yeah, the fit isn't right.
My interest in Parayko is to anchor a third decent shutdown pair and a third PK unit.
I'm skeptical about his cap hit fitting without messing up pp1, pk1, or pk2. Lars Eller seems to be mostly on PK1 this year, so already I have to make another trade to replace him. Luckily, some of the teams rebuilding have spare 3Cs, and some are cheaper, but they aren't upgrades on Eller.
Lars Eller was 5th in the 2018 SCF in points, behind Kuznetsov, Carlson, Backstrom, and Smith. His linemate, Burakovsky, tied for sixth. He's signed cheaper, for longer than Parayko. A one for one would be fair, but obviously if STL is rebuilding, they would prefer some picks/prospects/young players.
