The Pacers don’t exactly need to rebuild, but rather retool towards a very defensive team with the core of Simmons, Turner, and Brogdon.
The Spurs gain Sabonis, who would be a perfect fit in Pop’s system, and would elevate both Murray and McDermott playing off of him.
The 76ers gain a lot to get Simmons off their hands, putting White and LeVert around Embiid and Harris.
