It's smart to train 1B players who pickup a ground ball to step into the base path and run towards the batter-runner. If the BR reverses direction, all other runners must go back.
Smart defensive strategy to ensure other runners can't advance.

I did it this past year and it was even two teams within the same organization ('01 & '03)...it was very difficult. Had great AC's on both teams but I really believe both teams suffered from a lack of consistency in coaching.
Rare is the situation where this can work in TB.
