All that agility and skill works real good when you are standing in a ring ,playing by the rules and taking legal shots against each other. It all goes to pot when you are in a bar or tight spot and some mean as hell guy 100 lbs heavier jumps on you and you are flat on your back with him on top. Best you can hope for is if, and I say a big if, you can manage to get some sort of leverage hold before you get knocked out.
