LeBron James The Decision Part II

Four years after "The Decision," LeBron James appears headed toward another one.

The burning question: Where will the NBA superstar land next?

The Miami Heat star and four-time league MVP has decided to exercise his contract's early termination option, meaning he'll be a free agent July 1, a source close to him told CNN's Rachel Nichols on Tuesday.

What's the big deal about a basketball player possibly changing teams? James is a rarity, an athlete so dominating that his personality transcends the sport. He's earned first-name recognition, like Cher or Barack.

James' move would set up the 29-year-old star for a possible departure from Miami, where he has played the last four seasons, reaching four league finals and winning two championships.
