So, because you're biased, it means you weren't biased. Gotcha. There's the slim possibility that you're capable of hating both fighters at the same time. It's not like trying to **** and sneeze at the same time, after all. As far as the rule in question goes... ...Chazz Witherspoon probably has an opinion on that one.
A round is not over correct. BUT, the round is not going. Therefore the rule is not the same. Therefore Floyd did not get DQed. What was your scorecard?
In a somewhat relevant thought Mayweather was legitimately knocked down. That could have made the fight closer.
