16. Shaquille O'Neal
The Diesel is one of the more creative guys on here. He has talked shit about everyone from Kobe Bryant to Erika Dampier. He smacked Greg Ostertag before a game with no cameras present and referred to the Sacramento Kings as the "Sacramento Queens." Shaq also talks shit to Kenny Smith and Charles Barkley on TNT's Inside the NBA, forever throwing his rings and stats in their faces. And let's not forget about his ongoing fued with Dwight Howard. Even with his career having ended a couple years, Shaq still loves to run his mouth.
