Why the Pacers do it: They basically swap LeVert for a younger version of him in Gary Trent Jr. They get Achiuwa and 2 1sts for Turner (Rumors suggest they want one young player and 2 1sts for him). They also give Toronto McConnell and Holiday because Toronto is trading 2 very valuable unprotected picks.
Lineup: PG:Brogdon-Banton SG:Trent-Lamb SF:Duarte-Craig PF:Warren-Brissett C:Sabonis-Achiuwa
Why the Raptors do it: Raptors basically solve all their problems with this trade. They get a true big, they get a bench point guard and a bench scorer. They also swap Trent for LeVert. Even tho it does cost 2 very good picks, this is a very good trade for Toronto if they want to take advantage of VanVleet and Siakam's prime years.
Lineup: PG:VanVleet-McConnell SG:LeVert-Holiday SF:Anunoby-Barnes PF:Siakam-Boucher C:Turner-Birch
Why the Thunder do it: They basically are in this trade because of roster spot implications and they get Flynn and a 2nd to take on the Dragic contract. They buyout Dragic.
Lineup: No changes
Also note that Nando de Colo isn't part of the trade
