When you make your bones getting punched in the face for a living you want to make the most money possible every time out. That $8 mil was not solid and I'll give you the number one reason why: Arum would have made nothing off the match had it gone down. He would have lost money even. NOBODY knew who Margarito was and the only thing the 'most feared' was trying to do was build a rep for himself. Who had Margarito beaten up to that point who was noteworthy in any fashion whatsoever. Mayweather has time and again beaten guys who were in greater esteem than Margarito.
