One of the biggest revelations I've had over the past 24 months is that a lot of the actions that get taught happen naturally. IMO one of the actions that happens naturally is the opening of the front side. Two years ago at one practice I made sure to watch each girl on our travel team as they warmed up throwing overhand. To my surprise, the front thigh of every one of them rolled over prior to their front foot landing; just as Hodge describes in his video. That was enough to convince me that if the girls are taught to hit using the overhand throw as a model, the front side will open correctly automatically.
Ah, I see. I remember that from the Hodge segment posted on the other site.
