I have never been a fan of using the sprinter's stance to teach or improve drive off the rubber. I picked up a new student and her mechanics have been crippled by it. She's a first year pitcher, 11 years old. She bends too low, at the waist, and takes what amounts to a long step. She lands heavily on the front foot with her shoulders over her hips and collapses into her front leg. Surprisingly enough she has a fair amount of IR. Her dad told me that her previous coach used the sprinter's stance and stressed getting as far as she could off the rubber. By starting so low, with a bent back, she never gets stacked and has basically no front side resistance.
When addressing drive mechanics my first step is to use stair climbing to try and get them to feel the glutes firing rather than the quads. Once they get that I move on to the 2 step drill, then stand tall, fall and go.
