Yeah, they have Shesterkin and Quick. The idea is "Trouba has regressed to a 3rd pair defenseman who one could argue is a pylon. He makes $8.0m cap hit for 2 years. We're sending you two cap dump bad contracts with no prospects and MAYBE a draft pick for doing you the favour of taking on Trouba's terrible contract and cap hit".
NYR aren't looking at Husso as a goalie. He's just a negative value contract that they need to take on in order to get rid of Trouba. Then, they quickly move onto the next step, which is "how do we get rid of Husso?". That problem is way easier to solve than "how do we get rid of Trouba?". It's a one year deal for $4.75m. Just buy him out or pay a team a draft pick to take the contract. If you retain 50% on Husso, you can probably do Husso + 5th for a 7th rounder. That's not particularly painful.
OUT - Trouba and 5th rounder
IN - 7th rounder and 7th rounder and MAYBE a pick from DET
NOTE - retaining 50% on Holl (2 years) and 50% on Husso (1 year)
Rangers would just keep Trouba they won’t take that much in dumps
Retaining 2.5 is enough
