You would be hard-pressed to look for a much tougher player in the NBA than Miami Heat icon Udonis Haslem. The 41-year-old veteran is a real OG and very few players in the league today, if any, are able to match what this man brings to the table for his team.

Now in Year 19 of what has been a very colorful career, Haslem has pretty much seen it all. He's gone toe to toe against some of the baddest dudes in league history. However, when it comes to talking trash, there is no doubt in the Heat veteran's mind that there is nobody that comes close to Kevin Garnett:

“Much respect to the career that Kevin Garnett had and the success that he had,” Haslem said, via David Akerman of Heat Nation. “But the s— that come out his mouth sometime ain’t got nothing to do with basketball and is the most disrespectful s— I ever heard in my life.”

Even Haslem himself has to admit that Garnett has the dirtiest mouth in league history — at least in his own experience. It's no secret that the Boston Celtics legend is one of the GOATs when it comes to talking smack, but based on Haslem's statement here, it is clear that KG does have a tendency to go overboard at times.

Garnett has always maintained that he's kept his trash-talking at a “professional” level, but as Haslem reveals here, this just isn't true.
