I've watched a few Ducks games recently. Zegras actually looks pretty good now that Cronin put him back at center. His stat line sucks obviously, but the team is a total mess.
The Ducks have 7-8 guys age 23 and under playing significant minutes, and much of this inexperience is at crucial positions: center and defense. When the puck is in the offensive zone, they aren't poised enough to cycle and generate high quality chances. They have too many guys opting for low quality shots (ex: Cutter Gauthier shooting it from 40ft away all of the time) or turning it over, which kills the play. Then in the D zone, the young guys get exposed. Jackson LaCombe might actually be the worst D in the league right now, not Lindgren.
I think Zegras also is pissed at the Ducks for whatever happened during the contract negotiations and wants out. I wouldn't say he's dogging it, but a change of scenery is what he needs.
Furthermore, do you really want to roll with Brodzinsky as your 3C for the rest of the year? Othmann hasn't shown us much at 5v5. He could still turn into a really good player, but we already have Perreault and Berard in the system and close to NHL ready. Othmann played with McTavish in Switzerland during COVID. Verbeek likes pricks who finish checks. Trouba and Kakko are probably on the outs next summer, and trading them should help us recoup some draft capital.
Also unlike pretty much every other team, the Ducks have too many centers. They almost traded Zegras and a 2nd for Logan Mailloux and a 1st at the draft (basically 2 late 1sts). Othmann and a 1st should be more than enough for Zegras. Add in Lindgren and the Ducks can keep their 2nd rounder for 50% retention on Fowler, who is reportedly looking for a trade. IDK I could be biased being a Rangers fan, but I think this deal is feasible.
