Blazer, Jay -
If you swing in the correct pattern, the rear foot will commonly come up onto the toe. If you swing in a poor pattern, a common symptom can be squishing of the bug. (Often because it is taught!)
Outright teaching to squish the bug will almost ensure poor pattern.
Outright teaching getting onto the big toe will ensure almost nothing with regard to pattern.
When I saw this thread, I buried my face into my hands. Discussion in this format is not beneficial, IMO, at this time. I am writing a book. I am not posting here trying to sell it. I just want kids to have the best chance to be successful and when I see that not happening, I do things like bury my face into my hands.
Saw an awesome quote today that made me smile:
"You can't learn something until you accept you don't know it."
Marcus, perhaps you missed this post?
