There's been a lot of smoke between Anaheim and Vegas. Enough to where I believe it's a done deal as alluded to in the article.
As to what McPhee will get in return you're probably talking pick/s. Ducks aren't going to miss a pick, given how loaded their org is, and might have thrown a prospect in there as well. If Vegas doesn't take the guys they want to keep they're still gonna be loaded.
I'm thinking McPhee will sign Hanzal in the 72 hour window and that will give him his first and second line centermen. First two lines will be subpar at the wings, but down the middle, on the blue line, and between the pipes they can look pretty good if they get that done. Then load up a bunch of picks on top of that, and this thing will be kicked off in a fine manner.
