If they aren't known for their power than who is? I'm still waiting for these mystical fighters only you know about that have more power than the guys he fought or have a better chin than him. The only one wasting your time is you, making yourself look like more and more of a jackass.
You are the one who originally said he has no chin. English not your 1st language or not, that can only mean one thing. You realized you made a mistake and backed of your idiotic statement and in the process of trying to be right somehow, you've only managed to showcase how truly ignorant you are.
