This is a surprisingly solid deal for both teams involved, and is likely mainly to clear the books for the infamously bad Mozgov deal from Los Angeles' books with the anticipation of signing marquee free agents over the next two summers. It may also signal the Lakers' intent to sign a point guard, either via the draft or in free agency.
For the Lakers, this is longer-term play to clear space for Paul George and LeBron James pursuit. Lonzo Ball on way at No.2 https://t.co/KxfdEuAUO0
Brook may be in the Lakers' long-term plans, but is only under contract for next season, so could be an option to clear space for his new team as much as his old one. It is less clear what role Russell will have next to Jeremy Lin with the Nets, but the move in and of itself will probably have little overall impact on the value of the 2018 Brooklyn Nets pick controlled by the Boston Celtics.
