The 3 teams mentioned are the Clippers, the Grizzles, and Orlando. Let's make a trade idea for each.
Orlando Magic
Terry Rozier, Abdul Nader, and Marcus Morris to Magic
Jonathan Simmons and Shelvin Mack to the Celtics
The Magic wanted Terry Rozier last year in a trade for Serge Ibaka. That trade fell through because Brad Stevens and Danny Ainge really, really, really like Terry Rozier.
He continues to improve his game and efficiency with more opportunities, but it seems like he is the most likely to be traded (or you could possibly sub Marcus Smart in for Rozier in this trade). The Magic get a good young guard prospect and a veteran forward.
The Celtics get a reunion of Bulldogs (Shelvin Mack, Gordon Hayward, and Brad Stevens). Shelvin Mack has been sneaky good at running offenses in the NBA as a backup -- that's something we desperately need. We also get Simmons, an athletic defensive-first player with good driving ability. In this trade, we get a little smaller, but Simmons can hold his own (and did for the Spurs last year) as a small-ball 4.
Memphis Grizzles
Tyreke Evans to the Celtics
Marcus Smart to the Grizzles
This serves as a reboot for both teams and both guards. Smart is an upgrade offensively over their current starting guard (Andrew Harrison), and the Grizzles have had good luck with former Celtics defensive guards (Tony Allen). Smart could become a crowd favorite in Memphis, and the front office could control his destiny moving forward as a RFA.
The Celtics get more scoring off the bench which is a desperate need with or without Gordon Hayward. It would also be interesting to see what Evans will get in free agency next year after no one wanted him in 2017. Could the Celtics give him a 5 year, 40 million dollar deal? Would he say no? Would another team offer more?
Los Angeles Clippers
Lou Williams to the Celtics
Clippers Pick to the Clippers
This is the Clippers pick the Celtics obtained a while ago. Why not complete the circle and send it back to them. With the way it is going, it was unlikely to be a first round pick anyway, but this way, the Clippers own their own picks.
The Celtics get a scoring threat for their second unit. Although I'm not a big fan of Lou Williams, he may be the best option available.
