Telepathy would revolutionize the game, huh?
Imagine what that would do for football.
To clarify the point. What FP was saying was that when there isn't a runner on 2B (which is when a runner is in position to steal signs and convey them to his teammate at the plate) then there should be no need for a sequence of signs to confuse the would be sign stealer. So he was a little shocked that they were doing it with no one on 2B.
