Another thought:
The Red Wings look like they're going to have 5 picks in this upcoming draft all within the top 50. I'm going to wager that they're not going to keep all 5 and will look to deal one or two of the 2nd rounders or even the later of their 1st rounders for help now. No playoffs for them in seven years running now. The pressure is going to be on Stevie Y to get back in especially with their captain locked up. They'll look to make moves at the draft and this summer.
I don't see the Rangers trading Trouba this summer, but there may be a shock move (or two) that the Rangers may make this summer if they come up short of the Cup. I think they hesitate because Schneider hasn't been an NHL player since November. Still, it's something to think about, and the Wings will have cap space this summer.
The Rangers will need to move Goodrow to sign their RFA's.
Goodrow to Detroit for Detroit's own 2023 2nd rounder (no retention on NYR's end)
If the Rangers want to make a big move and think that Trouba's best days are behind him (FWIW, I think he's been fine since he's gotten over his injury), Detroit would be the only place I'd see him waive to.
Gustav Lindstrom. Anton Stralman lite. Get in on him before the secret gets out. Break out candidate written all over him.
Goodrow and Trouba to Detroit with no money retained for Lindstrom, NYI 2023 1st that Detroit owns, Detroit's own 2023 2nd.
Rangers clear $9 million of net cap space after paying Lindstrom 2 years, $1 million/season cap hit.
