The Daily Caller tagged Kobe as the most hated player in NBA history.
Bryant may have led the Lakers to two NBA Championships in a row, and was indisputably the second best player on the team from 2000-2002. From 2001-2009 Bryant had couple of fracas and scandals that put his name on the top headlines.

He also quarreled with Allen Iverson and Vince Carter to such an extent that they had to be separated by the referee.
The NBA superstar had a string of bad blood with his teammates too -- from Shaquille O'Neal to Pau Gasol, he often criticize them in media or fighting on ground.
Bryant and Shaq led the Lakers to three consecutive championships from 2000 to 2002. But a spat between them and a loss at 2004 finals made Shaq to left the Lakers. He always pointed to Kobe's selfishly attitude.
