Each team still has to lose a player. So, any trade has to make sense for the other team to also benefit the Canucks.
Take the Ducks. Understanding is that KB has a NMC, but the Ducks are permitted to ask KB to ask if he will waive it. If you are LV, do you want to select KB and his 1 year left on his contract or is there someone else on the Ducks you would rather have? More likely to be the latter.
Ducks have 5 good D in Lindholm, Fowler, Vatenan, Depres, Manson. Up front they have to protect Kesler, Perry, Getzlaf, Silverberg. Rackell is another who should be regarded as a protection target.
Either way, the Ducks will lose someone whether they go 7F and 3D or 8 skaters.
Canucks can't pick up a Dman without exposing an Edler/Tanev/Gudbranson. Unless they are going to trade someone like Edler at the TDL, if they fall out of contention.
If there is another expansion in 2019 or something, then that could impact the Canucks. But, by then the twins will be gone.
