What the...just run at him?? Have you ever seen Floyd fight? Coming at him with no defense at all is practically suicide. That's the last thing you'd want to do. That is the exact way to give him a chance to light you the fuck up. You really think Ronda could take hard shots from Mayweather?
Then you say Floyds best chance wouldn't be to box, it would be to knee her? WTF...are you trolling or drunk or what? Floyd is possibly the best boxer of all time. Think about that...the best boxer of all time, against Ronda Rousey. And your advice is for him to knee her?
C'mon dude...Floyd would light her ass up, and it wouldn't be close. Rousey is the Royce Gracie of her time. If WMMA stays relevant, she'll be surpassed.
And she'll never be anywhere near Floyds level.
