Practice Swings and actual swing

I have seen some good practice swings in my time playing golf, that seem to change once the ball is addressed. This chap Charles Barkley in the link below has quite a free flowing practice swing, but then when he addresses the ball... well have a look for yourself, I think this one takes the biscuit.

Whats the pro's analysis on this swing? 

If you want to see his practice swing you can see it in one of the links once you are in you tube titled Charles Barkley Golf Swing $1000 long drive.

Ah the old Charles Barkley Swing. I always give this link to our juniors to model thier swings on,they fall about laughing and comment's like I see where you got yours from Leyo heads my way  

It actually scares me Russsell, but I have seen worse a lot worse

wait till you eventually get to a NvS
