BoxRec

People seem to focus on boxers but athletes from other sports can also talk as if they were hit too much.
CBS' NCAA basketball show analyst and former NBA star Charles Barkley slurs his words like some boxers. Did Barkley take too many elbows to the head?

Have you ever seen Rory McIlroy in those television ads? It's not that he sounds punchy but he does sound ridiculous.

David Beckham. Just because he's so dozy and says "errrhh" after every third word.
