I think GS would trade KD in a nano-second for Zion. Get rid of a guy that doesn't want to be there for the next 15 years of greatness?Teams that would not trade their star imo...
Giannis
Curry
KD
Lebron (still put him on the list but with his age it's possible)
Harden
Westbrook
Paul George
Kawhi
Lillard
Simmons
Embiid
Towns
Doncic
Maybe you could add a couple other players depending on need of team, etc. (I didn't put AD on there bc obviously N.O. would trade him for #1 bc of the circumstance)
