Ali. He had that undeniable gift of finding that one thing that really bugged his opponent. He could be cruel especially when he was young. As he got older it was wasn't quite as cruel but he dominated the spotlight so much in the prefight atmosphere that his opponents felt like props for a play. Toney. Nonstop trash talking at it's best. But he does so much that it becomes comedic and loses the sting Ali had.
I hope you're not referring to Ali. That's a little below the belt even for a Golota worshipper. If you're talking about Toney. No one has shut him up yet. He's still talking trash.

Hamed was a pretty good talker in the UK. Never really seen much footage of him interviewed in the states. First time I've really seen Tarver talk was after the Woods fight that guy is crazy.
