Peden was overlooked BAD by Nate - Peden later broke Mayweather's ribs in sparring leading up to the Marquez fight.
Taunting can be used in exactly the same way as a feint....although it's more of an information gathering technique rather than looking to create openings although it will do if you know your opponent well enough and can get inside their head You have to know when and where to do it When Fury taunts he is always well out of range
The fight that I saw taunts the most was Leonard vs Hagler. Hagler was taunted by Leonard throughout the first 6 rounds. However, Leonard's taunts didn't go wrong. He did them well.
