I completely respect that. But I would suggest taking video of her for your own use. It can be a very useful tool, even if you don't post it. When you have some video to look at, keep an eye on her front leg and her hands. Does it look like her hands are going back and up while her stride foot is moving forward? If the hands are moving forward as a unit with the rest of the body, it would be an all back / all front pattern. Look at the video below of Ryan Braun to see if you can see the "separation" between his hands and his stride. Some people will refer to this as "walking away from the hands".(NOTE: The gurus will say that you shouldn't watch the front foot when looking for this, and they would be right. But if you are new at this, it may be easier to see that way. Most of the gurus here will tell you to watch the hands in comparison to the rear hip.)
As far as controlling the movement pattern, you will see a few potential explanations about that. I would suggest doing a search on "forward by coil". Others will say that you need to utilize the core to control the movement pattern. I would prefer to allow the experts explain both versions. In either case, you are trying to control the movement in order to time the pitch. Hopefully that is a little less muddy...
Good stuff - I see this hip coil that cabrera and chamberlin do - seems like cabrera drops his hands and then raises them as he coils his hip forward...do you advocate raising hands up slightly as the weight shifts forward?
