content: It would be interesting fight. Mayweather and Rousey are trained in two different discipline. Mayweather can diffidently knock her out with a good punch but boxing is limited on what you can use. Rousey is trained completely different. all she would have to do is dodge, knock him down, and get him in an armbar.  I think if they were fight, I would place my money in Ronda Rousey.
