I love Rowdy, but I think her beating Mayweather is a bit of a stretch. She dominates the women's division, but put her in against other men in the UFC and she wouldn't be as good. Sure, she'd beat a fair few of them, but not necessarily the top tier fighters. Throw in the fact her background is in grappling and she'd be only using her hands, I'd put my life's earnings on Money winning.
