For anyone not entirely up to speed with all things MMA, there's quite a formidable female fighter named Ronda Rousey around whom a significant amount of attention has formed. In MMA circles, Rousey is very much respected and feared. According to UFC president Dana White, pound for pound Rousey would be a match for almost anyone. It's easy to see where he's coming from.
For some reason, there's a particular fascination with hyping a bout between Rousey and Floyd Mayweather. White even went as far as saying that Rousey would beat and badly hurt the multi-weight boxing champion in a street fight.
When he was finally asked to give his take on the claims that Rousey would beat him, Mayweather's response was typical of the man who nicknamed himself 'Money', he doesn't know who 'he' is.
