Jeff Hammond is a great competitor, coach, and school owner straight from the Caique lineage! He has won tons of competitions and runs his own school in Texas, but more importantly, he's an awesome teacher with great techniques.
In part three of the series, he expands more on the position from the last video and how to actually hit an armbar from the position. This works great if your opponent is really fighting the sweep, and who doesn't love submissions? He really hits all the little details you need to make this work and shows how it would work in a live roll.
