I don't know which is dumber - doing the drills as described by the original poster, or putting it here for the whole world to see. Kind of like bringing the rope to your own hanging, no?
I can only say that I hope there are some concerned parents or staff members who get this guy out of the dugout pronto, before he kills someone.
And, I hate the notion that you think you are doing the right thing because you've won a few games. If winning is the only objective, if you are okay with the idea of putting kids at risk (in practice or games), I can only be glad that you aren't coaching my kid.
There are enough inherent risks in baseball without intentionally putting any player in harms way. You are a danger to your players and should be fired immediately.
