I could never harbor a personal grudge against a player based on a bad performance. But when a guy self-promotes his own free agency signing "special", then goes on talking about how "easy" it will be for them on the court, as well as the 7+ titles they're going to win (at least 1 more than the GOAT), it puts a bad taste in my mouth right from the start. Then he had Nike confiscate the tapes of Jordan Crawford dunking "on" him @ his camp that summer, which I think everyone would agree is a super douche move. THEN, in a full-on hissy fit, he made a commercial taking shots at Jordan and Barkley, in a childish response to criticisms made by both. And finally, after losing the Finals, he goes on national TV blasting the fans for pulling against him, telling us all to go back to our "same old ordinary lives", etc. He just seems like an immature, arrogant dude who can't understand, or tolerate, anyone not riding his jock. In fairness, it doesn't seem that he had much parental guidance from his trainwreck of a mom, what with her out getting DUIs, fist fighting valet attendants and taking frequent trips to Pound Town via Mr. Delonte West.
On the court, his constant over-celebrating and "mean muggin" irk me to the bone, and while I know that traveling and flopping are both things that NBA refs generally choose to ignore, it still bothers me to see how often LeBron flagrantly gets away with both, and yet still cries about EVERY call made against him.
Just not an easy guy to like if you don't live in Miami I guess.
