That is true. Size does not matter. My high school team that one the state championship had to face some tough teams. Our offensive lineman averaged about 5' 10" and 240 pounds and our half back and quarterback were only about 5'8" and 170 pounds. The reason we won was because of the coaching. He used a system were he taught the players angles and correct blocking schemes. He ran a wishbone type offense and we were beating teams that ran spread and other similar offenses. We even beat Matt Jones and a couple of other good players to get the title. That was when Jones was still a quarterback.
