1. Bradley Beal
While it may seem odd putting Beal as an option for trade considering the Suns have only just acquired him, it makes sense and is a likely option to be considered if Giannis becomes available. Beal is a star player and rounds out this big three nicely, however Giannis slotting alongside Durant and Booker would be even sweeter.
This move could be made possible dependent on where the Suns and Bucks both sit come the midseason. If Beal is not working out, the Suns may try to ship him off and see what they can acquire.
Likewise for the Milwaukee Bucks, who may see their superstar talent request a trade if the team is not performing up to standard. While some other pieces may be needed from the Suns, the Bucks would get a decent return if they took an offer for Beal.
The star shooting guard averaged 23.2 points and 5.4 assists per game this past season, showcasing he can be a playmaker while also being the main option on the offensive end. He would slide in well alongside Holiday in the backcourt and have a number of solid players alongside them, including Middleton, Brook Lopez and Bobby Portis.
The Suns would become even scarier, with a frontcourt trio of Giannis, Durant and Ayton dominating opposing big men. The team would also have superstar teammate Booker running the backcourt.
While it may not seem likely that the Bucks trade Giannis or the Suns having the best options if it did occur, Phoenix should certainly make an offer if the time arises. Any of these three players could be enough to seal one of the best players of all time.
