Pacers: For the pacers, they add Powell, who can shoot and couple play off of Levert and defend a bit better then Brogdon. He'd help their spacing and be able to defend a bit better so it'd be an upgrade. They'd also get Seth Curry, a elite 3 pt shooter to help with their shooting and then also get Covington who is a very solid defender. These moves would upgrade them because they'd upgrade shooting and defense, two big needs.
Grizzlies: It's just waaaaaaaaay too much value to turn down, probably should have added in Tyus Jones here.
76ers: If Dame is happy with the Blazers, and then beal isn't gettable for them, this would be a good move they would make to upgrade their backcourt. McCullom is a great 20pt. scorer, and the brogdon would run the point guard position. Losing Curry & that first is too bad, however, it'd be worth it to significantly upgrade their backcourt.
Raptors: The Raptors add a true 5 with Nurkic and get picks and cut down roster spots.
Blazers: This would give them more lineup flexibility they could have Simmons at the 5 and play the point center role and then they got Warren, Brooks and Nance starting at the 2-4. They'd have plenty of scoring (Dame, Warren, Brooks) and then the defense with Simmons, Nance, Brooks) they'd need to get a true 5 rather then Simmons if they are facing a team with a true 5 though but that'd be it.
