I played HS football in Texas. While playing JV we once played a team that called the play at the line of scrimmage. "Dive Right. Dive Right. Go." or "Sweep Left. Sweep left. Go." or "Option Right. Option Right. Go." It was very frustrating to know what was coming and yet see them still get 2-4 yards. They were actually a fairly good team and we ended up tied 0 - 0. But I still remember the frustration of not being able to stop them more often for a loss. Their execution was very good.
