Jazz: May not be willing to part with Markannen, but if they are, this would be a strong return. A recent 1st rd pick and two former 1st rd picks made by Ainge, along with 3 future 1sts. Probably a long shot considering their current wealth of picks.
Celtics: Move would push them over the top as the favorite title contender with Butler being a better fit next to Tatum and Markannen pushing Horford to the bench.
Heat: Realizing they don't have a team that can win it all, they move Butler before he declines from age and add two players in their 20s who will combine with Adebayo and Herro to make a strong core for the next 5+ years.
Likely a long-shot, but would be interesting for all 3 teams.
