1. Dwight Howard, L.A. Lakers
Dwight Howard went from one of the most lovable guys to one of the most hated in a hurry. He has no one to blame but himself. After the Summer of LeBron, all attention shifted to Howard's situation in Orlando. First he said he wanted to stay, then he said he wanted to leave, and then he said he wanted to stay again. His indecisiveness went on for several months.
When the 2012 season ended and it came down to signing an extension, Dwight finally made up his mind and was dealt to the Lakers. He also jacked one of Shaquille O'neal's many nicknames and he smiles too damn much during games. Sometimes it seems like Dwight doesn't care whether he wins or loses. He's the type of guy to enjoy a good prank after a blowout loss in the playoffs. Get mean, Dwight!
