I find it funny the people that keep talking about Mayweather... this is the problem with UFC and Dana White. He doesn't actually give a fuck about his fighters. It's about entertainment and money. I think he pushes fighters to do stupid shit against their best interest.
If Rousey (apparently she knew exactly how she'd go down (http://www.usatoday.com/story/life/entertainthis/2015/11/15/ronda-rousey-ufc-ko/75825926/) played it like Mayweather she could have just let the fight come to her. She's the champ, decisions would go her way. Instead she attacks the girl knowing she's going to get frustrated and knowing she could get "kicked in the head"
Weird, stupid, and who the fuck is to blame for it? Mayweather never did something like that.
What? Mayweather has fought world class talent his whole career. I'm still not sure why this concept is so hard to grasp.
