Thanks Patrick and O.B. for this discussion. The drill of getting into that static impact position (I guess it is really dynamic if one is actively exerting pressure)seems to be a wonderful way to test the efficiency of one's grip. I'll use it on my boys at practice.
First day of high school practice is tomorrow. "C'mon boys, I'd like to introduce you to some flying wedges, some pressure points and some dragging mops.
I'm so excited I'm breaking out in hives.
