Oral Thomas, is above the kneck, head the bodys biomechanics stablise it volentary its the bodys job to do so 2 major things that give us balance are the inner ear and our big toe depending on there allignment tells us whether someone is in balance, simple example is when someone is walking. Its the first thing we do when as a child we learn to walk its a natural trait. most good balaced fighters box in there walking gait with the back foot turned to suite shoulder movement and defence and punching mechanics with the back foot being able if it had an eye to see the other guys chin. Tito in the photos back foot cant see vargas chin so he starts with a wide left hook in that position the body recruitment pattern will make him drop his right hand for balance bad technique bad balance trouble. In fairness vargas isnt much better hes all over the place too
