Always hated youth coaches that taught this stuff. Coaches should be spending their time teaching the fundamentals of the game...not this stuff...trying to steal runs because the opponent is too inexperienced. As you rise up ladder in the sport, that stuff doesn't work, so why teach it?
At the higher levels of the game (college), any delayed steal situation would result in the runner from 1st getting either caught in a rundown or getting the runner from 3rd out at the plate. Not always, but enough that you seldom see it attempted.
