I'm not in the CIA, even though I look like I am. We are good friends, so you shouldn't screw with either of us. But, this is not about the CIA or me, it's about the best boxer who ever lived. I'm just curious as to your opinions. Most amateur boxing fans would say 'Mike Tyson', so don't bother with that one. As much as I like Floyd Mayweather, i'd personally have to say Sugar Ray Robinson was the best. What about you? Cassius Clay? Joe Louis? Who do you think is the best?
