This reminds me of an old story from high school. Back in the day, our school was somewhat of a powerhouse. We ran the ball like 98% of the time, and the signals coming in from the sidelines couldn't have been easier for opponents to figure out. This one particular game, my cousin was the QB. He ran up to the head coach in the first quarter to let him know the other team "figured out" our signals and knew what plays he was calling. Coach says, "I'll change them if they can figure out how to stop us". We averaged like 15 yards a carry that game. Coach is in the high school HoF.
