Nuggets 5: Russ - Murray - Butler - Gordon - Joker

Cavs 5: Garland - Don - MPJ - Mobley - Allen

Heat 5: Herro - Levert/Strus/Jaime (start 2/3 at SG and SF) - Bam - Ware

Reasonings:

Nuggets are about 1 piece away from being a legit contender (you could argue they already are), so giving up some future draft capital, MPJ, and two borderline scrubs who don't play for you (and Zeke Nnaji's horrible contract) for Jimmy Butler, who has a great playoff track record, is a great deal for them and propels them into a probable WCF birth at the very least.

Cavaliers are steamrolling all of the east and have lost just 7 games all year, but there is a pretty good chance if DON, Garland or Mobley get hurt, the team starts to fall off a little. Giving up two top of the bench guys for MPJ, who adds another great scorer to the team to fill in the void at Small Forward (started 7 players there this season if my research is correct). Not to mention they get a second which is always cool.

Heat: The heat get some alright bench pieces back here that could probably have them stay in the late lottery, but they get off Levert next year, flip Strus likely and there is a LOT of free cap. They get a 2026 first and a 2028 first both via Denver, which might seem like "not enough" for Butler to some, but with how publicly disgruntled he is, I think 2 FRP for Butler will end up being enough and probably what they end up getting

Suns I know are getting linked with Butler a lot, but I think the cap will end up working out weirdly and they won't be able to get a deal done.
