Does Mayweather have any take down defense whatsoever?
If they fought under UFC rules, I'm pretty certain Ronda would just take Mayweather down and win by decision (I don't think she'd make him submit but I think he wouldn't be able to do much down on the mat with her)
If it was under Boxing rules, I'm pretty certain Mayweather would knock her out
This is why I don't get the whole "MMA Vs Boxing" thing
They're completely different sports with different rules and regulations
It's like saying "Wayne Rooney wouldn't be able to do a thing if he had to be wicket keeper for Lancashire this season"
Well yeah, of course he wouldn't. It's completely different to what he's doing now. I think if you took Mark Rampracash and told him to play at centre forward for Man United, you'd get a similar outcome
