The Jets could be forced to trade one of their D - either Trouba or Myers - to get the most value out of the expansion draft rules (7F 3D 1G), but I personally don't think that there's a depth player on the Jets that is worth protecting more than the top 4 D the Jets currently have. Here are the expansion eligible players on the Jets that qualify for the expansion draft:
Mark Scheifele
Bryan Little
Blake Wheeler
Mathieu Perreault
Alexander Burmistrov
Shawn Matthias
Marko Dano
Andrew Copp
Joel Armia
Adam Lowry
Toby Enstrom
Dustin Byfuglien
Tyler Myers
Jacob Trouba
Ben Chiarot
Michael Hutchinson
Connor Hellebuyck
There are others in the farm system (Kosmachuk, Lipon, Howden, Kichton, Melchiori, Olsen), but the likelihood of LV taking those over an NHL roster player is pretty unlikely. Out of all of those, if the Jets do trade a D to enable them to protect 7F and 3D, I predict that they go with this:
Scheifele
Little
Wheeler
Perreault
Dano/Armia (pretty interchangeable at this point, so will come down to who Chevy values more)
Lowry
Copp
Byfuglien
Enstrom
Trouba/Myers (whoever isn't traded)
Hellebuyck
That's if they value their depth pieces more than the extra D protection. Personally, there isn't a depth option on the Jets that is worth protecting, nor is it remotely difficult to replace the player you lost in the expansion draft.
4F/4D/1G
Scheifele
Little
Wheeler
Perreault
Buff
Enstrom
Myers
Trouba
Hellebuyck
That leaves Matthias, Burmistrov, Copp, Lowry, Dano, and Armia exposed. Matthias was signed expressly for the expansion draft (either to entice LV to take him or to help fulfill the draft rules). Those are good players to expose, but nothing worth losing sleep over if they are exposed and one of them is claimed. Still, for a cap conscious team like the Jets, the idea of losing assets for nothing is a heavy concern, which is why they could very well trade a D to make it easier for them to protect more forwards.
Anyways, those are my thoughts for the Jets.
The NHL isn't dumb; they'll see right through that and assess a penalty to a team that tries to play cute with that.
