Sure but you ignore all of the games he comes out at the end of blowouts. You focus on a game here or there and put your negative spin on it. I mean looking at the Lakers scores, I see Lebron coming out of the January 15th loss to Denver with around 8 minutes left. He came out against Memphis on January 9th also around the 8 minute mark. The December 23rd blow out against the Spurs he came out with about 6 minutes left. The December 21st game against Phoenix, he came out with about 3 minutes left when Paul, Booker, and Ayton all left the game. December 17th against the Wolves, about the 5 minute mark.
I'm not seeing a lot of games where Lebron is staying in until the bitter end when the Lakers aren't in the game. Lebron doesn't play in the blow out losses at all.
