AD, even not at full strength, is exactly what the Lakers need on defense, especially help defense. Plus it would be a fun end to the saga. Because Ayton prefers the midrange, the Lakers can manage the double big thing.
Luka - Reaves - Lebron - AD - Ayton
The Mavs get Quickley and picks in the deal for the future of their guard rotation.
Raptors get two forwards who help with shooting and defense in their rotation, plus take a flyer on Knecht.
This might be more fun than practical....
