Orlando - whoever they draft #1 is a PF. Carter Jr is a solid defender but he isn't great. He can however shoot & is on a relatively good contract. If the pick is Smith or Chet, they should pair them with an inside force like Ayton who will finish possessions with good rebounding & defense. Aytons offense is still developing but Orlando pairs him with their starters of Cole, Jalen, Wagner Rookie PF, Ayton - that's a good core that may even make the playoffs this year. They also dump the Trumper's 3-year contract for another dead weight contract in Danny Green's expiring. For Ayton, they had to deal bench depth in Fultz, Rozier & their current starting C in Carter Jr but should Ayton get there this is a great deal.
Sixers - Need wings & a bench G. Get both. Trumper & made of glass or not they need size & defense. Dumping Green's contract & a few other guys including last years pick is worth it.
Suns - Carter Jr can shoot. Fultz has upside at 23 & at worst is a bad contract good bench G who can still develop. Ross is a bench spark plug.
