50. LeBron James
Team: Miami Heat
Hateful lowlight: "The Decision"
Most great athletes are hated on some level, but there seems to be a special kind of disgust for LeBron James. Between exhaustive Michael Jordan comparisons, The Decision, and becoming a 270-pound poster child for the NBA's flopping crisis, James draws more objections than George Zimmerman's attorney did. Is it fair? Probably not. But if you're going to get "The Chosen 1" tattooed on your back and stage an NBA coup in Miami, you better be able to handle the wrath of trolls on Twitter.
