I think LeBron got fed up with ESPN's loose lips, dropped a false rumor on them that he was returning to Miami and stood back and laughed as it spread like wildfire across the entire organization. Now they're getting their revenge and showing their power to create a narrative that other lazy members of the media (TNT) can't help but pickup.
Check out SI for instance (the organization James selected to publish his return announcement). Chris Mannix was recently asked whether Kevin Love should stay in Cleveland, and his reply didn't even mention any reports that Kevin wants to leave, it just said that he's still an elite player and that the Cavs have to re-sign him. He said these sorts of questions "made very little sense".
James may want to re-consider, and kiss and make up with ESPN, because while he can handle the heat ... the rest of the team doesn't really need it. I suppose he knows the best answer is always just to win.
