Think about if a QB calls a screen and all the sudden the MLB yells "watch the screen. watch the screen" and the play gets blown up because they saw what was coming. Next the QB calls a draw and the MLB screams "watch the draw. Be ready for a draw" and the play goes nowhere. Do you think complaining to the league office would get any sympathy? No. The offense needs to change their signals. Same with baseball. The best deterrent to sign-stealing is to keep changing your signs.
I miss the old Mile High Stadium.
