My feeling on LeBron is that he's more than good enough to win a championship, or multiple - if he went his whole career without one he'd be in close competition with Elgin Baylor for greatest ringless player ever. It'd be a shame to see a talent like that fall short for his entire career.
But I don't want him to win one until the league humbles him, until he realizes the game is bigger than he'll ever be. If he ever gets a title, I don't want to see him dancing and strutting with the trophy, I want to see him crying with it, like Jordan did. I'm not sure he's there yet. Either way, we're in his way, so better luck next year!
