I could see teams using this to gain an advantage; they look for every edge they can get. If you think it would be too contrived, consider this example: In a 1951 baseball playoff game the New York Giants (who later moved to SF) contrived an advantage over the Brooklyn Dodgers (who followed the Giants to the West Coast): If I remember correctly, the Giants placed someone in center field (outside the field of play, behind the wall) with binoculars. He would read the catcher's hand signs to the pitcher, indicating the next pitch. They buried a wire from center field to the first base or third base coach, which would vibrate something under his foot signaling the pitch to him, and he would signal the batter. Nobody knew until 2001 that when Bobby Thompson hit a legendary game-winning home run off of Ralph Branca, sending the Giants to the World Series, Thompson knew ahead of time what pitch was coming (a very large advantage for a batter). Would a team use 2015 technology to gain an advantage? They wouldn't even need to bury a wire.
