Never one to let go of a meme, the UFC is still stoking the fires of the could Ronda Rousey beat Floyd Mayweather conversation. Starting way back in April of 2014, when Joe Rogan appeared on SportsNation and fielded the question, the UFC has never since been able to quite tear itself away from the narrative of Ronda Rousey vs. Floyd Mayweather. In part that's down to the athletes themselves. Mayweather has been slowly goaded into playing along, starting with his claims that he didn't even know who Ronda Rousey was and getting to the point now, where he's challenging Rousey to prove she can make as much money as he has.
