You could probably get better picks out of it, but I think it's a move that NJD should consider -- they won't really be competitive for a couple of seasons, so there is no harm in taking on that cap for 2 years. And it will come off the books the same year as Subban which will give them a big chunk of $$ to spend that off-season.

Perhaps, OK if we are talking a Summer 2021 deal.
If a trade like this were to happen, it would have happened already. Likely before the draft, before free agency.
No reason to do this type of deal until next off-season.
