Well rousey is a great female fighter and ambassador for the sport I think she has been WAYYY overhyped because how quick she has been finishing the best the ufc could throw at her. The talk about her being able to compete with 135 and 145 pd "men" was ridiculous and premature. Especially coming from people like Joe Rogan.

Then she ran into the well trained and "very" experienced striker that is (holy holm) and we got to see those short comings in her striking game disastrously exploited.

That being said she is an amazing judoka athlete.She also probably walks around at about 150 considering she cuts to 135 for bw, so she nor her counterparts are 105 Pds. I would guess ronda and Floyd are closer in weight than you think.

The thing about judo and jujitsu both rely on using your weight and ballance against your opponent. In other words if ronda got a hold of mayweathers arm she knows how to put all of that 135 pd frame into that one limb.I think if they were to fight in an octagon or ring Floyd's footwork would make it impossible for ronda to close the distance, but if mayweather just tried to"grab her by the throat and throw her down " like you said, he could very well end up with a broken arm.
