Yes, Im sure he is demonstrating "something". However, what do you believe the "something" is, that he is demonstrating?
Is this a photo of Ben actually swinging? Or is he demonstrating/practicing a drill? The position he is in, in this photo, appears different from many of the other shots of him at this stage in his swing. Also, he appears to have a club on the ground behind his right foot with 2 balls lined up along the shaft. Did he just drop it there or is he using it as a reference point of some kind?
