This is all from a personal perspective
The Bucks get the ideal package for Giannis, from Jon Horst's eyes, almost everything.
Bucks
You get a BUNCH of young players, and your picks back and a 2032 Hawks pick, which depending on how they do could be valuable.
With getting your 2026 pick, that means you can get to tank this year, and get yours and NOLA's pick, which might also be bad.
With the addition of Myles Turner, you could even just retool for a year, try to develop Bufkin a little, or try to find that piece to get you back into contention.
Your lineup could be PG- Kevin Porter Jr/Kobe Bufkin/Trade for a point guard SG- Dyson Daniels SF- Zaccharie Risacher PF- Jalen Johnson C- Myles Turner
Hawks
Yes it looks like you gave up a lot, but thats the value that a top 3 player in the league has, and how you see it, you might get off easy by only sending three firsts.
Giannis still has a good 7 years in him left if he stays healthy
With the additions of NAW and Luke Kennard and Newell, you can still contend with not losing ALL of your depth
Your lineup could be PG- Trae Young SG- Nickeil Alexander-Walker SF- Asa Newell PF- Giannis Antetokounmpo C- Kristaps Porzingis
