I'd do that

Honestly I'd make Montreal pay more than any other team considering how marketable he would for them

I wouldn't trade Laffy for anything that doesn't include Byfield ++ coming back.

New York easily declines.

Pieces like Romanov, Suzuki, Kotkaniemi, Caufield, Peohling & your 1st rounder(s) would have to be involved for NYR to even consider. Obviously not ALL of them are needed to make it work, but atleast a couple would be required

Do you think we’d look into moving Kreids?

nah

The Rangers have 3 good options depending on the preferences of the 2 teams picking after them.

a) If the Kings want Stutzle at 2 (it means they really want Laff) and are willing to deal a haul (1 of Vilardi/Kaliyev/Madden/Fagemo AND a 2020 2nd or 2) then you move down to 2 and take Byfield and net the haul from the Kings and hold Kreider.
b) If the Kings want Stutzle at 2 AND Ottawa is willing to deal 3 and 5 to get Laff, you move down to 3 and 5 and take Byfield and one of Raymond/Rossi at 5 and hold Kreider.
c) If the Kings want Byfield at 2. You hold onto the #1 pick, Take Laff and deal Kreider for a similar deal as was available at the deadline (1st + Jost +)

Moving Kreids would make signing UFAs in the future more difficult don’t you think?

nope. not at all.
