THE CELTICS PROBABLY DONT DO THIS BROWN IS INPORTANT TO THEM AND I DONT THINK TH FRONT OFFICE IS WILLING TO DO IT
PACERS: The Pacers offered Brogdon and a future FRP for Simmons, and because your first offer is never your last offer, they would have given another FRP for Simmons. Basically, would they rather have Simmons, 13, Turner and 54, or Jaylen, Grant and a FRP? For me, it's defintley Jaylen. Adding Brown gets them another forward who can defend, score, pass, and rebound, and a great all-around scorer. Simmons does solve the Pacers defensive problems, but he makes their shooting worse with having 0 spacing, the only good shooter being Warren and that would create a nightmare on that end, and solve their point guard problems. However, Brown gets them another scorer in addition with Levert, and Sabonis. Also, this gets them a lineup that fits better, which should be important and Simmons chocked, not Brown.
HORNETS: Thompson would be a solid backup 5, and in addition they'd get a pick in this draft, and it's a really, really, really deep draft so they'd do this. They could also decide if they want to extend him or not.
SPURS: The Spurs do this because they could lose Demar for nothing, or get a FRP for it. They'd agree to a buyout with Horford
CELTICS: I'm not saying they should do it, or will do it, in fact I said that it's for a user and they probably don't do it. However, if they do it, then they would get the 13th pick in a great draft, they interviewed many players that should go in the 13ish range. Also, they'd fix their 5 problem with getting Turner, and getting rid of their 2 fives and getting Brogdon who could be a point guard if Smart is injured as they have basically nobody besides Pritchard, who is a shooter, or Langford who can play a tiny bit of point guard but should be a emergency point guard.
They'd have Smart-Brogdon-Demar-Tatum-Turner
Pritchard-Langford-Nesmith-a 4-Timelord as their next backup 5
They would target a 4 in the draft, probably like Kai Jones or Moses Moody in the draft.
