there is still a hard deadline for this: December 1st
If Lindholm isn't signed by then, he can't play for the remainder of the year, and this hurts both the ducks and Lindholm. On top of that, the longer the ducks wait, the more the AAV for this season is going to go up. Ducks only have several hundred thousand $ in cap space to play with, so even an AAV increase of $400k this season can make or break this for them.
Beyond that, The ducks need to sign him in order to start winning games, so yeah, there is definitely a deadline in play here.
Trust me, if the ducks wait, they are going to find themselves paying a FORTUNE to get a team to take on a $3M cap dump in Stoner (which is a small cap dump considering the cap ceiling--about 4%). They're going to find themselves in a VERY similar situation to the blackhawks where they're going to have to cut bait with a very good ROSTER player (not just a prospect) in order to make space for Lindholm--nobody is taking on Stoner as a favor.
There was also a SERIOUS lack of foresight on the ducks part. They could have had this space available without paying the price of a promising prospect for it if they had just bought out Bieksa this offseason.

For Trouba, different situation, but same end result. It affects the team and the player (and the respective values of each component).
Everyone knows about the deadline. It's not going to force their hands considering they're only about 700k apart according to Friedman. For them to make room for 5.5 mil is not going to require them to trade Fowler for scraps. They have options.
I don't disagree that there was a serious lack of foresight on the Ducks part. They made a huge mistake re-signing Bieksa before he even played for them. Hell, they made a mistake trading for him in the first place with the contract he had and what he wanted.
All it's going to take to get Lindholm in at 5.5 mil is assigning Larsson back to Frolunda, assigning Sorensen to San Diego, and potentially LTIR'ing Despres and Thompson to buy them time if there isn't a deal that is sufficient for them.
