In the games since, LeBron James’ defensive effort has further wilted. His aggression has waned. His frustration has grown. And his leadership, which at times has been controversial in its style but never questioned in its intent, has faded. He is absolutely culpable; his past month has been one of the worst of his NBA life. This comes after the first two months of the season in which he was a leading candidate for MVP. Which makes his erosion all the more clear. And the Cavs are culpable for allowing the trust and the relationship with management to crack. The Cavs know crisis better than anyone — they’ve been immersed in it on and off for four years. But this is a different situation. Everyone can feel it.
