The game's biggest star will now lead a young Lakers team — run by Lakers Hall of Famer Magic Johnson — that has been overmatched in recent years while rebuilding.
But the Lakers will instantly rise with James, a three-time champion who after being swept by the Warriors in this year's NBA Finals said he is still driven and very much in "championship mode."
Los Angeles will also provide James with a larger platform for his business interests and social activism. He already owns two homes in Southern California and has a film production company.
This is the third time in eight years James has changed teams. After bolting from Cleveland in 2010, he returned in an emotional homecoming four years later, determined to make the Cavs champions.
The 33-year-old had previously said he wanted to finish his career in Ohio, and although he's leaving again, Cavs fans are more forgiving after he ended the city's 52-year sport title drought in 2016.
Why the Lakers suit LeBron: Salary-cap space; business interests; iconic franchise.
The Lakers add a superstar to a team featuring up-and-coming talents like Kyle Kuzma, Brandon Ingram and Lonzo Ball, who is reportedly dealing with a knee injury. James loves the Hollywood lights, and with two homes in the Los Angeles area as well as a film production company, he has already established some roots in the land of movie stars and slow-moving traffic. The appeal of playing for one of the league's most storied teams is another allure.
