Why is LeBron James a sore loser. After every loss he is the first one to walk off the court and never congratulates the other teams. Ever since he started his career in Cleveland he's been doing it. Many people have noticed this besides myself and some are Lakers fans and don't like LeBron. Pass this on to Ernie, Shaq, Kenny and Chuck. Go back to beginning of career. One year he walked off before game was over.
