LOS ANGELES — LeBron James has been very good at basketball for a very long time. Beyond all the points he has scored and the rebounds he has grabbed and the championships he has won, it is worth remembering just how much time he has spent plying his trade.

Now in his 17th season, James has supplied more than 48,000 regular-season minutes, which ranks among the top 10 on the N.B.A.’s career list. At 35, he is the 10th-oldest active player in the league. Even so, he has shown no signs that he is approaching the end of his career. His production defies logic.

“Just remarkable,” Doc Rivers, the coach of the Clippers, said before his team faced James’s Lakers on Sunday afternoon at Staples Center. “I’ve never seen a guy get better at 35 in sports. It’s just unusual. I mean, he’s doing something right — he really is. Because he looks stronger and faster.”

James proceeded to overpower the Clippers in a 112-103 win, finishing with 28 points, 9 assists and 7 rebounds as the Lakers kept rolling. It was their second win in three days against opponents who are, like the Lakers, championship contenders. On Friday, the Lakers eased to a 113-103 victory over the Milwaukee Bucks. All James did in that game was collect 37 points, 8 assists and 8 rebounds while putting the defensive clamps on Giannis Antetokounmpo for key stretches of the second half.
