The problem is the Rangers need cap space themselves. You have less than $7mil to sign Trouba, Buchnevich, DeAngelo, and Lemieux which is st least $15mil.

Ok think I finally got this right...And why do you trade a guy that you can bury in minors for another guy you bury in minors with a much larger cap consequence and same 2020 UFA status? Plus Winnipeg has $22mil in cap space to sign RFA's Laine, Connor & Pionk. They don't need a cap dump.

It’s a $825K hit.....

I'm speaking from a Rangers perspective.
Yes, Beleskey's hit is $825,000, but you're trading that for Kulikov's which is $3,258,333.
From Capfriendly:
What is a Buried Contract?
Teams do not receive full cap relief when a player on a one-way NHL contract is reassigned to the American Hockey League, or is loaned to a team in another professional league.
The players salary cap hit, minus the sum of the minimum NHL salary for the respective season and $375,000, still counts towards the team’s salary cap total.
The cap hit relief is therefore equal to the minimum salary of the respective season + $375,000:
2019-20: $700,000 + $375,000 = $1,075,000

Beleskey - $1,900,000-$1,075,00 = $825,000
Kulikov - $4,333,333-$1,075,000 = $3,258,333
