LeBron is still a very good player but it is clear that he is not the best anymore. Throughout the season a 2-3 years younger LeBron would win these type of games and he has struggled all season.
His first step is slow, maybe he is 300 pounds like people say. His layups are not going in, and his shooting has been inconsistent. He needs to lose a lot of weight and try working from the post.
His whole stretch during the last 2 mins was embarrassing, just iso basketball or holding the ball for 20 seconds but that is what Lakers have ran all season with LeBron. I will give Luke some blame there too, 1 v 5 basketball with this LeBron does not work.
