An exposive push is the key I think. My daughter went from 6'2" to 7'9" in stride length and every thing I told her to do to get there didnt work. Then one day some random guy told her to speed up her drive leg. Make the back knee stay up with your back hip. Since then she has learned to just glide out. Have to get that glove hand high as well to get that weight off of the drag leg. Has been a great aproach for my DD. If you have a huge stride but are doing the splits it will slow you down and screw everything up. Having said that I understand, there are great pitchers sticking that big side of the drag foot in the ground, so that method must not be bad at all either, just always looked like it could run the risk of injury to me so i chose to find some one who taught to glide. Speed is up not to mention when the ball comes out she is a ton closer to the batter.
Java source has some really good stuff. He gets really technical which is great. My daughters coach has a way to get allot of the same things across in a really simple way that makes light bulbs go off and go oh ya, without confusion. Java has allot of good video clips in I believe drive mechanics. He can correct me if I am wrong.
Not knocking the straight Drive leg. This is why a great pitching coach realizes not every student is the same. When you are small you have to figure out how to fly! This is a technicality that goes to different pitching styles that I have seen. Jenny Finch locked leg, A freak by size and athletisism. Just one example. Any way when you are 6' plus how far can you really leap and drag. If she did what my daughter does at 5'5" she would be 6+ inches out of the circle AT LEAST!I saw the Drive Mechanics thread about the drive leg becoming straight while stride knee is bend and in the air.
Nope... your right... my stuff is great! lol
The cue your PC is using is actually a really decent one. You cannot gather your drive knee under your rear hip unless you've exhausted the push early. The effort needs to be spent before the movement can get going.
"Driving out as far as you can" is only as effective as the interpretation. MOST younger pitchers associate this as a reaching movement... not a power movement.
