This is more like the Ducks going full re - something else.
You are sorely mistaken if you think this series of moves puts the Ducks in a better position. A rebuilding team should be looking to add pieces like Gibson, not trade them for a bunch of crap.
There is a really bad misconception around here that a team needs to go complete full tank in order to get better. Trading all your best players for a bunch of non elite prospects and late 1sts has a very low chance of making a team better at any point. Anaheim doesn't need to get any worse in order to get better, and they are not hurting for young depth whatsoever. They need more high end core pieces, so trading off the few that they have for all this stuff is completely ass backwards.
Rebuilding teams generally don't build around players who will be outside of their primes by the time they are relevant again, no.
Dislike it all you want but full on tanking is an excellent strategy and knowing the difference between that and teams who are just terribly ran is an important distinction as well.
I do agree that Ana is a pretty bad team either way and will get a high draft pick regardless.
You seem to be the one who is confused on how rebuilding works though, not me
