Bucks:
Bucks get 4 All-Star prospects. Plus 2 weak FRP.
current lineup - PG: Rollins, SG: Ivey, SF: Jacquez, PF: Holland, C: Ware - this team can compete in the Playoffs from day one.
They are also getting 2 big Expiring contracts taking 53M from their Cap
Heat:
Miami becomes a contender on day one. With this lineup, they can win at all.
Giannis is surrounded by 5 ~40% shooters (Mitchell, Powell, Hero, Wiggins, Turner), so the team already fits him. And no FRPs were given, so there is still room for maneuver.
Pistons:
Bam goes back to his better position as a PF. A perennial DPOY candidate, and a great offensive force who can now even space the floor, shooting 0.357 from 3 in the last 3 years on a rising volume.
The FRPs will not be missed, and Ivey cannot be afforded anyhow. Holland, on the other hand, brings a lot of energy and defense, but is a worthwhile sacrifice to a team that wants to win now. And Bam is on a whole other level.
