I don't think Bergevin will bite on that Silverberg trade unless its a sign and trade, however I'm sure hes all for that Alzner trade.

Definite no to silfverberg, habs don't need wingers.

Yes yes yes yes yes to the alzner trade, are you sure!?

I put that last trade in for ****s and giggles. Eaves hasn't effective at all this year and the Ducks just need to bring new young forwards.

Is Silfverberg really worth a 1st? Not sure but maybe, I do think the Ducks should trade him at the deadline and not bring him back, he's a good player and I like him but it's time to bring in some new faces to that lineup, younger faces.
You're not moving Kesler or Perry unless you want to sacrifice some key assets so might as well improve the roster around them, maybe look at buyouts in another season or two but until then they're yours, should just ride Eaves contract out at this point.
In my opinion if the Ducks really want to turn this around quickly and really transform the roster they'll look at moving one of Lindholm or Manson. I realize they're the teams two best defenseman but the Ducks have a strong D core so they could afford to part with one. The Ducks two most valuable assets are those two, trading one for a massive haul will get them their best bang for their buck so to speak.
I know most will say otherwise but tweaking around the edges or trading secondary pieces isn't gonna make much of a difference to this team.
