Love these vids! There’s so much to be learned from them.
For beginners who have only watched down the line or caddy view footage of swings this is a real eye opener.
If you watch down the line stuff only, you can easily be fooled into thinking that you should try to recreate those lines you see. If you try that you WILL come over the top, or at least disconnect the arms from the body. The golf swing is not about straight lines and this shows it.
