EXACTLY!! Sometimes I have to restrain myself from walking over and whispering "Slow down... slow down..." The sad thing is the coaches are oblivious to what is happening, or how hard it is to unlearn that junk!
One of my DD's pitching coaches always stressed to approach a practice pitching session (lesson) with a purpose; a plan. Don't just mindlessly throw pitch after pitch, but each pitch should be a feedback mechanism. Did you get the desired result? Did the pitch drop or curve? What do I do to fix that? Same way with soft toss. Did I weight shift properly? Did the ball go where I envisioned it? (you did picture the ball going somewhere didn't you?) Did you finish and follow through? It's called perfecting your practice motions, so your GAME motions will be just like them - only automatic.
It sounds "anal", but if drills are done sloppy, the game performance will be sloppy. It's a discipline that should be learned by any kid wanting to advance their game.
