According to Sporting News, Lebron might be willing to sign in LA without Kawhi Leonard or Paul George being on board first:
In the reporting, Deveney cites a league executive saying that “he expects James to sign with the Lakers, even before the team remakes its roster” even in the midst of buzz that James is communicating with other top-tier players about a partnership. “That’s the sense you get with him and his people,” the executive told Sporting News. “They’re doing enough research to suggest that he’s going to be willing to take that plunge and let the roster come together. It’s what happened in Cleveland four years ago.”
The Lakers talented will be limited around James anyway because of the outgoing players in a potential Kawhi Leonard trade.
