If you remove Adam Henrique, I think both sides agree with this trade.

Indeed. 100%

Anaheim has two seconds and three thirds this June, all of which are likely to be earlier than the Islanders pick, so those selections are unimpressive and carry little weight (at least, to the Ducks). Anaheim should get a better offer for Adam Henrique with 50% retention elsewhere; given how well he's been playing with Pavel Mintyukov, that package might not be enough to persuade the Ducks to part with Ilya Lyubushkin (whom Anaheim might end up re-signing).

The 3rd and 5th would get you Bush

Which leaves Robertson and a 7th for Henrique at 50%
The ducks will want more.
