Lebron James started off his NBA basketball career in 2003 when he was picked first by the Cleveland Cavaliers at 18 years old. He was the youngest player to win the NBA Rookie of the Year award! He got a lot of crap when he switched teams and went to the Miami Heat in 2010, in his first game with the Miami Heat against the Cleveland Cavaliers, the fans of the Cavaliers were throwing things from the stands at him, calling him all kinds of names and hating on him. That did not stop James from doing what he does best, play the game. He is in my opinion the greatest player to ever play the game of basketball!
