For someone who is as self-conscious about his image as LeBron, I can't even begin to fathom any scenario in which he leaves. None. He's got two All-Stars around him. He's got great role players. The team has signed two of his buddies to contracts and appears willing to pay Thompson more than he's worth.
If he leaves again, there is likely no recovering his image. It's not like the first time around where league-wide there was a perception of the front office not doing enough to surround him with talent (not my view, but other people who don't follow the Cavs). They've given him literally everything to succeed this time around, he went public with his desire to play and retire here and has reiterated multiple times that he wants to finish his career here. His kids want to be here. His wife wants to be here. The fans here love him like fans of no other city ever could. He certainly wasn't as revered in Miami as he is here.
It's one of the great stories in sports. The prodigal son returns home and all is forgiven. Now he needs to cap it off with delivering a title to a city starved of them.
The only people considering that possibility are the fans that still feel uneasy about what happened a few years ago (understandable to a certain extent), and those across the league that want the Cavs to fail and want to watch the city of Cleveland slip back into sports misery.
He's not going anywhere. Neither is Love. You can quote me on that and I will eat crow for days if I'm wrong, but I'm not.
