All you have to do is watch them fight.....just look recently at Pacquiao........the KO punch was thrown with his head down, not looking at where he was throwing the punch......... looking at the ring floor......typical southpaw......
Damn . . . you people should not make it hard for yourself . . . who among those names in the list attained the highest stature and has the highest accomplishment? . . . it's gonna very hard and illogical to justify against that.
