I don't know why anyone would think Mayweather was the big reason for the fight not happening. In the end, it didn't happen because Pac wouldn't agree to the 14 day cut off date, and since that time Bob Arum himself admitted they were wrong for not agreeing to it, and didn't agree to it because him and Pac were "ignorant to the drug-testing stuff".

I understand people don't like Mayweather and are going to tow the same old anti-Floyd rhetoric until they die, but the facts are the facts: there was ONE demand that kept the fight from happening, and one party came out and admitted they were wrong for not agreeing to the demand, and refused due to their own ignorance. Who do you blame there?
