Answer
The answer is the James Harden trade. In January 2021, the Brooklyn Nets acquired James Harden from the Houston Rockets in a blockbuster four-team trade. As part of the deal, Caris LeVert, along with several other players and draft picks, was sent from Brooklyn to the Indiana Pacers. This trade significantly altered the rosters of multiple teams and had a major impact on the NBA landscape during the 2020-21 season.
