They'd probably hang up right away. I'm willing to wait 2 years also, it's not a big deal. Knowing PLD wants to leave, and wants to specifically go to Montreal really sours his trade value to other teams as he's only seen as a 1-2 year rental at most. So you're essentially paying for 2 years of RFA years for PLD. Clearly, none of the young key players are going to be included as both teams know it's not worth it. Right away, they're going to ask for a few picks, probably 2-3 mid tier(2-3 Rd) picks. Then they'll ask for a centre to replace PLD. Dvorak is the only sensible option. Then they'll probably ask for a mid winger in the vein of a Gallagher, Armia, etc. Habs would want to alleviate cap so I could actually see them giving away Anderson if Armia is also combined. A B-level prospect will probably also be included.
So I can see PLD for:
Dvorak, Anderson, Armia, 2nd, 3rd, B-Prospect
