On Friday, he opted out of the final year of his contract with the Cleveland Cavaliers to officially become a free agent.
The Cavs can offer a five-year, $205 million max deal, while the Los Angeles Lakers have four years and $152 million on the table.
No one will know anything until 9 p.m. PST at the earliest, when the NBA free agency window officially opens.
