No reason for Florida to do that.

Both Florida teams decline. Kovacevic isn't an improvement over what they have and Crozier is also NHL ready so they offer maybe a 6-7.
Lundell is really a priority in Florida.

That Florida trade seems like the baseline. As closer the draft gets and more information gets known about where the Jets pick will be around 22-25OA and the prospects profiles becoming well known.
It's a price each team should be able to live with and follows the Newhook trade model. Florida would be able to sign Reinhart and Montour without having to negotiate the new Lundell deal and use the pick as collateral for an older replacement to Lundell ala Ross Colton.
Then, have their cheap young RHD, Barron, to replace the old vets they brought in over the Summer like OEL, Kulikov.

I have Hutson as the 7th D and PP specialist. The Habs go with 11F and 7D for much of the year.
Dont think you need to bring up Reinbacher so soon. Keep him cooking with Mailloux in Laval.
Keep Xhekaj-Savard.
Get Guhle away from Matheson. Play Harris on the right.

This is precisely how I see the trade for Florida.
