Not a chance Winnipeg considers moving their first for low end players.

WTF would Chevy do this?

Winnipeg has a log jam at LHD so I highly doubt they would be interested in adding one more and trading away one of their two right handed dmen. Also I don't think they are in s position to trade their first round pick this year.
Also why trade for a player just to have him as a healthy scratch? Demelo is a good defender, may not be flashy but he's a solid bottom 4 player.

Trade simply doesn't make any sense for WPG. This deal heavily favours MTL.

I assume the decision would've followed a severe hit to the head.

Explain me why they can’t consider this

1. Logjam at LD
2. Morrissey doesn’t like to play his offside and the only one comfortable doing so is Schmidt.
3. Monahan isn’t a 2C
4. Jets need To keep their RD
5. DeMelo is underrated and is a great shutdown D who can play up and down the lineup and is on a great contract
6. Jets are in no way whatsoever in the position to be giving up picks or prospects, especially this year with how deep the draft is.
I could keep going but I would hope that you get the point that the Jets neither want your junk or to give up assets

This really sums it up. You named 7 defencemen and only one is right handed. That is more than enough reason to not do that trade for the Jets. I doubt they want Monohan either, at least not at that valuation.
