That's according to ESPN's Max Kellerman, who believes Kawhi Leonard is the player James needs in order to win a NBA title with the Lakers.
The 2019 free agency market could completely re-shape the league with the likes of Leonard, Kevin Durant, Klay Thompson, DeMarcus Cousins and several other top stars potentially joining new teams.
The Lakers currently have enough cap space to offer a max contract, putting them at the front of the queue for any prospective free agents.
They have been linked with a host of names, but one target they missed out on trading for this past summer was Leonard.

The San Antonio Spurs were reluctant to trade the 2014 NBA Finals MVP to a fellow Western Conference team and set a high-price for teams such as the Lakers.
Ultimately, the 27-year-old ended up joining the Toronto Raptors where he has helped them move top of the Eastern Conference.
He hasn't yet spoke about whether he would want to re-sign in Toronto or look at entering free agency.
But Kellerman believes the Lakers should try everything in their power to convince Leonard to join them.
The ESPN analyst goes on to state going after Thompson wouldn't be the right answer.
'I think you've got to hope and pray and do everything you can to get Kawhi Leonard,' Kellerman said on The Lowe podcast
'Kawhi Leonard gives you a shot.
'LeBron and Kawhi might win a championship.

'LeBron and Klay will not.'
The Lakers endured a torrid start to the season, winning just twice in their opening seven games.
But they have turned a corner since then, in part due to the addition of Tyson Chandler, winning seven of their previous nine encounters.
James will make an emotional return to Cleveland on Wednesday night when the Lakers take on his former team at the Quicken Loans Arena.
