I think Ottawa was willing to give up the most, they liked Brassard is from there, his contract was front loaded, and he fits right in with Turris also being on about his same level and age. They can have two scoring lines using those centers with likely more consistency than with Zibanejad.
The deal for the Rangers made sense, they got younger, potentially a player that will be as good, and they got a pick, even if I am not sold on Zibanejad, we'll see what he does in my opinion.
If they are using that sort of deal as their template, Rangers and Ducks are looking for the same stuff although I'd guess the Rangers are looking for it specifically on RD now, yet players like Vatanen, Tanev, Ceci, Trouba, etc are going to be near impossible to trade for, so they'll likely have to draft or find a player that has not come close to breaking out yet to try to acquire.
You're last paragraph basically describes Brandon Montour, I've been saying for awhile that he's probably the guy who fits the Rangers needs most.
