I would think the Ducks say no, because that deal really does nothing to help them with their salary cap problems. They need to move Fowler so they can sign Lindholm. This deal saves them less than 700K
Fowler doesn't have any effect on salary problems this is a common misconception. Moving only Despres gives them enough cap to sign both Rakell/Lindholm, then there's Stoner who can be packaged with a good draft pick for free as a cap dump. But again, Despres gets it done and he's an asset with decent trade value.
The Fowler for winger trade rumors stemmed more from Anaheim needing a top-6 LW, they have 0 of them right now. They let in the least goals in the NHL last year, Theodore is rapidly improving and montour is knocking on the door as well as larsson and pettersson down the line, so that would simply be a hockey trade not a camp relief. Also, it's a future move as Fowler will probably be walking to UFA and he would waste a protection spot in the expansion draft.
How can a guy making 4m who's worth more, the ducks most cost-effective/bang for buck asset, be traded in a camp dump? That's like Chicago trading duncan keith, their most bang for buck contract, to save cap. That's the last player you move in a cap dump. Despres, Stoner, and many more players go first if its simply a cap move.
Ducks are in win-now mode. The only way a player like Fowler goes is for a high-impact winger.
