What interests me is that it is a one plane swing by the look of it.
I was a child of the Golden Bear era and it seemed to me that this position was meant to be a new trendy position, compared with the 'traditional' position with your hands higher, for the two plane swing.
IIRC it was only in the mid 90s that the one plane swing came to the forefront because of guys like Jim Hardy, and his one plane vs two plane ideas, which eventually led to centred golf and S&T.
Of course, there's nothing new under the sun, and all these new inventions have been tried before.
Now I'll never know whether to think of Alliss as a traditionalist, or an innovator.
