I do not consider this something that will happen, but it is something.
LeBron is like George W. Bush, in a way. He is obsessed with his legacy, how he will be perceived and stacked against the greats. That's why he bailed a stagnant situation in a tone-deaf manner, because he knew he could get further by subverting the normal GM team-building process.
His goal, at least right now, is at least 6 titles. Jordan set the modern standard, because the talent today prohibits a dynasty like the 60s Celtics. As such, he now knows that he's up against a historically great rival in Kevin Durant, with several future HoFers just a short tier below.
Will he tire of being the necromancer to the lich Flash, and what of the rumors that Bosh wants to star somewhere else?
If he could somehow will his team to a third consecutive title this season, you have to bet the above will weigh on his mind. If you think about it, Kyrie is like some bizarro inverse of Russell Wesbrook. Hawes could be a younger, more terrible replacement for Bosh, and Dion has shown his ability to belong in games with peers with skills. Thompson could be traded for a young backup SF perhaps, one exclusively defense-oriented. I guess what I'm saying is LBJ could, while maybe never getting to 6 rings, do something that Jordan or anyone else ever could: win consecutive titles on different teams.
