Dude you ever fight.... I mean ever and not against your sister that shit doesn't count. Put it this way, if you had any understanding or experience you would realize how stupid your thread sounds. Basically MMA fights can most of the time make a good one dimensional striker look like trash in mma because they have many more tools at their disposal to take that striker off his game ( wrestling, jits, judo, sambo, etc). The same cannot be said if you put an mma fighter in a boxing ring because you have taken all those tools away from him now. I must also mention that while an mma fighter practices many disciplines (judo, jits, wrestling, kick boxing, boxing, sambo, tkd, kung fu, karate, etc) he will not get as good as he could at one single one because he spends his time on so many different training regiments. A boxer boxes and strength train and runs and boxes and gets much better at boxing than a mma fighter. When you put an mma fighter in with him with boxing rules he will teach that mma fight how to box. I hope this helps you make sense of your thread. Now go to gym and start training something.
