The thing that changed my opinion towards Lebron is all the stupid criticism he got for the cramps. People actually saying he's unconditioned and out of shape and a quitter. I found myself sympathizing for him. On the one hand I get really tired of an athlete when it's all hype and all the talking heads discuss. See: Tebow, Manziel, Lebron, Kobe, et al. It's unfair because they're being hyped for their talent but I still judge the player. On the other hand, however, I get all pissy when the talking heads refuse to focus on true team greatness and even individual players who just don't meet the criteria for being cool or hip or having street-cred. The Spurs, the Bulls (to a lesser extent- the Derrick Rose Saves the Planet schtick gets old), etc. Tim 5 Rings Duncan will only make $1M more than Tiago Splitter next year. Yet we can only talk about the Knicks, Lakers, and Heat.
The thing I see about Lebron going back to Cleveland is that it's like he packed his shit, went somewhere else to get the thing Cleveland the City has been waiting on since 1964 (at best) and forever at worst. Those fans know Lebron's rings are Miami's not theirs. And only the diehard delusionals are thinking he can win a title in Cleveland. Prodigal son. But really, him going back isn't going to change my opinion of him.
