Is lebron still the best two way player? I can make an argument that he is already in decline. He had his worst defensive rating of his career this year, worst offensive rating since his rookie year, the worst shooting year since he was 23, least amount of win shares since his rookie year, and worst PER since he was 23. If you look at most advanced stats, they suggest Curry, Paul, Harden, Davis, and Westbrook are all better players.
Lebron is still great, but you can argue he isn't the best player anymore. Is that because he is bored with the regular season and maybe doesn't care as much as the younger guys, and he just wants to focus on the playoffs? Is he wearing down at all?
He isn't nearly efficient as he was 4 years ago, some due to wear and tear, some probably due to not being entirely focused in the regular season, but even last night when he scored 33 he was "only" 13-29 shooting.
