In general I have been a big LeBron fan. Obviously an amazing player and athlete, and for someone who has spent so much time in the brightest spotlight (since he was 17), he has handled himself very well. He usually says and does the right thing, has been very charitable with is $$$, and he has never had any of the major screw-ups like many high-caliber athletes have had (Kobe sexual assault case, Jordan's gambling issues, Tiger's sex addiction, etc.).
His behavior the last few games has dissappointed me. Leaving his teammates early is a really bad look, as is not shaking hands at the end of the series.
