i was just about to say that, he would talk **** to you in spanish with no remorse or fear, just look at him vs Vargas,OScar, and everyone else in his big fights.
Mayorga has been named twice. I find his act to be more "forced" and sort of a pose. Part of Tyson's intimidation was that it was just NATURAL. The way he looked at you in the ring, that was him. Not a pose, not a show. One guy who would scare me, oddly enough, was Ray Leonard. Not a scary looking guy, no menacing grin or piercing eyes. Just an unmistakable air of confidence. Always looked anxious and excited to get it on and you could tell he wasn't acting or playing games.
Vitali and Kessler's stardowns are downright intimidating! Sometimes Kessler laughts during the stardown but he is still scary as hell!
Stare down doesn't mean anything. No professional fighter is scared of a look in the eyes. SOme try to look tougher. But none are impressed.
