Unless I missed something, both the '21 and '23 pick are top-4 protected, although I haven't seen anything on how those picks are conveyed if they fall in the top 4. I believe I read the other day that if the '21 pick ends up as a Top 4 pick, then the first 1st rounder goes to 2022 and is Top 3 protected. I have no idea what happens if the Bulls also retain the 2022 pick.
