In fact, I find that the more educated a bucket-dad/mom (can't forget them!) becomes... the less they flap their mouth.
This has definitely been the case with me. I flapped my mouth much more a year ago, especially two years ago, when compared to how I am now. I instruct at pitching practice, but I'm not saying much, not compared to what I did in the past. Sure, it has to do with my pitchers having improved, but it also has to do with the fact that I'm a lot more educated in pitching now.
