For everybody saying LeBron quit, I don't think he quit but instead got tired/gassed.
Y'all gotta realize that Bron is pushing 40 so while he can still perform at a high level he's not going to deliberately play the way he used to and singlehandedly dominate as he would during postseason runs in Miami or during his 2nd stint in Cleveland because he's trying to preserve himself and at this stage he doesn't feel he needs to which is understandable.
That's why for many seasons he tried pushing AD to takeover and he take a backseat position on the court but AD not being consistent enough Bron has had to exert energy just to keep us afloat. Sure, if we had a 28-29 year old LeBron type of play on this team we'd probably be better but at 39-40, he's not going to tire himself out and risk injuries at this stage.
