As a teenager, LeBron James was successful and achieved almost nothing in basketball.
After being drafted straight out of high school by the local Cleveland Cavaliers in 2003, James has been instrumental in the success of every team he has played for. Personally, he has the ability to change and direct the game, which is reflected in 12 NBA All-Stars, 4 NBA MVPs, 2 NBA Finals MVPs and the fact that he is the all-time top scorer in the Cavs.

His time in Miami also received some impressive accolades. James won the NBA Championship twice and also led the Heat to a 27-game winning streak, the longest in NBA history. The 32-year-old has appeared in seven consecutive NBA Finals since 2011, winning three of them, and looks unlikely to stop anytime soon.
