Look at his average this season. https://www.basketball-reference.com/players/j/jamesle01.html
He is worth a lot of money because not only he will make a team popular, but at the same time he can always assure that he will play with consistency.
For business side, the team who will acquire him will gain good numbers of fans to support tickets and PPV
but long-term wise, I'm not sure if that's a good idea though we can't tell what might be his future decisions.
Yes, this is true!
I agree with @Ziskinberg said.
Comparing with his past performance, unfortunately it is not in his prime.
He's just turned 38, he still plays like an allstar player, and is without a doubt still one of the best players in NBA.
That's insane, a 38-year-old player playing better than other young players and, above all, without a serious injury in his career.
In my opinion, I even believe he will be able to play 3 more seasons in NBA without losing too much his performance
