When you are boxing learn about boxing and what makes it work. When you are learning about MT do MT. That to me is the great mistake of MMA, people are so often trying to go and mix 2 or three arts together _before_ they have even bothered how to do one of them correctly. Once you understand how box like a boxer, roll like a BJJer and do MT like a "Thai", then you can start mixing them together and get something truly dangerous.
I figured as much. I was hoping for a more detailed response...or more over a specific experience.
