As for the Rick Reilly article...this paragraphe from him epitomises the stupidity of his argument(s).
"But I think the reason you hate LeBron James the most is that he just doesn't seem to suffer his failures as much as you'd like him to."
-- Well Rick, he "suffered" his failures enough for a) the Decision b) the Hall of Fame performance in Game 6
"You want him to brood like Kobe after losses,"
-- Lebron was the brooder who once left the court after defeat, refusing to shake hands
" glare like Jordan when things don't go his way, scream at teammates like Tom Brady when they're behind."
-- Funny, this is exactly what he's done in 2012, showcasing leadership
The majority of Lebron haters can be explained the same way you have Kobe Haters, Tebow haters - most of the fans of these players are insufferable and try to put their idols above reproach.
