From LA Kings

2017 First Round Pick (LAK)
LD Jake Muzzin
C Nick Shore

Not really looking for dmen

Think the Rangers would prefer Kale Clague over Jake Muzzin, tbh. Muzzin is obviously proven but think they would want to go younger with their return.

You're looking at a Yandle level-return as a starting point. So a 1st, a 2nd, and a Top Prospect. Realistically, with McDonagh's contract and rep as a Top 15 D in the league, it'll be even more. 2+ 1sts, a top prospect, and a Middle 6 F or 2nd pairing Dman is likely the minimum

If it's prospects only

C/RW Michael Amadio
LD Jacob Moverare

We'd still have to include an NHL-er, or the salaries won't match.

I don't think Rangers would take that deal. Low 1st & 2nd rounders, and 2 former low 3rd and 4th round picks? Rangers can get far better

I kind of agree with this. Not that you'd probably want to deal him to NYI, but:
1) Higher of NYI or CGY's 2018 1st
2) 2020 1st (contingent that McDonagh resigns with NYI after 2018-19) If he doesn't it becomes a 2020 2nd
3) Michael Dal Colle
4) Thomas Hickey (pending UFA, middle pairing d-man but should NYR want to extend it should not cost more than the $2.5M AAV Brayden McNabb just got)

If Rangers move McDonagh they should be looking to get a top 6 center
