Well I doubt Pommenville is going to just waive his NTC out of the kindness of his heart.
This is a business, we'd likely have to tack on a couple more guaranteed years.
I think they could make the argument as followed:
1. "we talked to LV, we know they are gonna take one of the D men"
2. By you waiving your NTC, we keep the team even stronger, thus giving us a better chance at a cup title.
Again, if you have a choice between Scandella, one of Dumba/Brodin, Haula and Pominville, you would be insane to take Pominville from that group. He's not a bad player, but he doesn't have near the upside of the other 3.
