Softball pitchers do not get the difference, as they have so many other variables going on (and I don't really want to argue about why, it just is), and yes, in the old days 2S peels (or other pitches) were used all the time, as hands were smaller and perhaps you could say ignorance or not. Many just dropped, no tail, and did so really well. I can tell you from swinging the bat against them in our team's BP. We had one. The drop was plenty enough...
As expected your experience in HS is much different than others. Just because you or your pitchers do not "get it" does not mean it does not work well for others. You seem to regularly sell you players short. Maybe all they lack is proper instruction?
