I think the big thing for Chevy is he has to look beyond this season. The Jets could get liquidated at the end of this season in a similar way to the way they did in 2019.
And he has two big contracts of core players heading into next season looming, in KC and Lowry. I don't suspect he would go the own rental route.
The 2nd has already been traded, for Toffoli. The 4th has been traded. How much draft capital can the Jets use up? Jets are already banking on a good draft year last year, with only 4 picks. But there's a development period that seems necessary for most of them, so that's a couple of years away from hitting the ice with the Jets. A guy like He may bypass that, mostly because of the position he plays, but I would think the rest are going to need development time.
If you replace Ehlers with Lambert, and Pionk with Salomonsson, that's a good test of depth already, and defensively there is none. The best case scenario would be Heinola stepping up, and Salomonsson moving in to the lineup. You can bring Lundmark back for one more season before he become a group VI free agent. The lack of draft capital is going to thin out the Jets. And you would need to draft a quality defenseman in 2025 to be able to replace De Melo in 3 years, with no immediate replacement for Miller, unless Lundmark makes the team one day.
That's where I wonder if a kid like Chibrikov gets put on the block. If the team doesn't see him as top 6 forward, which will have some competition next year with Yager and Lambert, maybe he is expendable as an asset.
The one that I look at beyond Ehlers is KC because that one can't be renegotiated until TC next year, if he sees the team lose players, would he be more inclined to jump ship and go to Detroit to join all his Michigan buddies that he skates with offseason. I think he'd cash out big in Detroit. So there are a lot of moving parts between now and the end of TC next year. The way Chevy plays his cards will be interesting.
