Ducks don’t need an elite or Top #1 D, they need the best compliment pairings for Drysdale and Fowler for those two to be able to play their game, and then eventually for Zellweger. I would not trade Zellweger for Chychrun, who may even have a higher upside than him.
This will get some heat, I honestly don’t think Lindholm was the most ideal D partner for Drysdale.
Drysdale has #1 potential, get him the most ideal pairing where he can reach that potential. If the Ducks bottom pairing ends up being Vaak - Helleson, with players above them being better and in a higher tier, the Ducks will be in very good shape on D. If those two can reach their potential, it won’t sting at all when they need to fill in a Top 4 role due to injury, which has been the biggest issue the last 3 or so years.
Drysdale's best position would be 3rd pairing at his age and experience. Lindholm is at another level, but Lindholm was the safest pairing for Drysdale. Drysdale with Fowler means no one's winning pucks in the corners often and both will be pinching. Drysdale with Benoit or Mahura sounds as disastrous as sounding it out as that would be an all-rookie 3rd pairing. Drysdale (LD)-Shatty is something we saw last year and no... just no.
I used to think Drysdale had top pairing potential, but not #1D. Lindholm was NHL-established in his D+1 season where as Drysdale is still feeling his way around. Drysdale has a long way to go to improve his mass and endurance.
D+1 seasons
Lindholm (NHL): 78 games, 30 pts (6g +24), +29 (2nd highest on team, 1st highest for D-men)
Drysdale (NHL): 70 games, 28 pts (4g +24), -20
Heck, Lindholm left the team with +0 rating this season.
I'm not very optimistic that we'll have a great D next year. It's a growing pains year.
