Los Angeles Lakers superstar LeBron James is considered by many as the best player in the game today. The 33-year-old has accomplished pretty much everything throughout his illustrious career. But just recently, James surprisingly claimed that his 2011 Finals loss at the hands of the Dallas Mavericks is actually what he considers to be his greatest achievement to date.

Speaking on HBO's sports and entertainment series called “The Shop,” James shared how the loss had such a significant impact on his career.

The summer of 2010 saw LeBron James make “The Decision” to bring his talents to the Miami Heat. Forming one of the most dreaded NBA superteams ever with Dwyane Wade and Chris Bosh, LeBron and the Heat had a remarkable season that saw them finish second overall in the East. They were just a few wins behind top-placed Chicago Bulls who were then led by season MVP Derrick Rose.

The Heat went all the way to the Finals where they would face the heavy underdogs Dallas Mavericks. With Dirk Nowitzki at the forefront, the Mavs achieved one of the biggest upsets in recent history by defeating James and his Heat 4-2 in the Finals.

To most who saw James as the ultimate villain for turning his back on the Cleveland Cavaliers, this loss was some form of redemption for what they believed to be an injustice. However, this was certainly not the case for LeBron James.

Sure, this was one of the low points of his career, but the fact that this only made him stronger as both a basketball player and a human being is a testament to the type of mental fortitude James possesses. This, perhaps, is one of the most significant reasons why he is one of the greatest to ever play the game.
