I doubt it matters that much. The only times in the last 15 years that a top-12 pick was traded:
1. when we knew where the pick would be;
2. for other picks;
3. it wasn't a team moving one or three spots down; and
4. didn't involve expansion draft shenanigans.
was when San Jose traded down from 11th in 2022. And that required a unique draft year with high uncertainty, and a team deciding to transition to a rebuild and lacking current a recent pick capital. The Islanders may fit that description, but if they decide to rebuild then they have veterans they can move and if they decide not to then its unlikely they trade down that much.
