TCMA does not deal with the reality of ground fighting. What "some" have posted as "evidence" is flimsy speculation on things they have never done. You have to know something before you can comment on it in a knowledgeable manner. (ground) TCMA presents a bland overview of techniques that do not delve into deeper work in that sector. My opinion and it will stay the same unless someone can present me with "hard" evidence to counter. It's not a bash on TCMA, most of the stand up is great, it has many priceless contributions in the MA world.

Boxing doesn't have ground work. You don't see all these boxers getting all bent out of shape when they are told they don't. They agree.
