Why 76ers do it: They get rid of Ben Simmons and create a solid starting lineup of Maxey-Seth-Tobias-Kristaps-Embiid
Why Mavs do it: Kristaps obviously is not going to be that 2nd star for the Mavs so they get someone who could in Simmons. They also get Bagley to see if a reset can jumpstart his career.
Why Kings do it: They get rid of Bagley and get good value back.
