According to NBA insider Marc Stein, as many as three superstars could be playing for new teams next season: LeBron James of the Lakers, Kawhi Leonard of the Clippers, and Giannis Antetokounmpo of the Bucks. "Expect their futures to be a major talking point throughout the spring," Stein wrote. James (averaging 20.9 points, 6.1 rebounds, 7.2 assists) is set to become a free agent this summer, and his future with the Lakers is far from certain. Although nearing the end of his career, he has shown he can still perform at a high level. It remains uncertain whether he will continue to do so in the purple and gold, with speculation that he could return to the Cleveland Cavaliers. As for Leonard (27.9 points, 6.4 rebounds, 3.6 assists), several factors could lead him away from the Clippers. From the NBA's investigation into his contract to the team's shift toward younger talent, the days of this 34-year-old in Los Angeles could be numbered. The future of Giannis Antetokounmpo (27.6 points, 9.8 rebounds, 5.4 assists) in Milwaukee has been debated for nearly a year. The 31-year-old has been at the center of trade rumors, and this summer could bring a final separation. The Bucks parted ways with coach Doc Rivers on the final day of the regular season, which could signal major changes coming in Milwaukee. He is reportedly being linked to the LA Lakers.
