Here's some great, but different footwork put on display by Gay Brewer and Billy Casper.
One thing I'm a firm believer in is that footwork is extremely important to the golf swing. The feet often cause the knees to make their action which causes the hips to make their action. That's your lower body pivot right there.
It's funny how many instructors emphasize the lower body starting the downswing, then completely ignore the footwork. If your footwork is bad, then you're starting off on the wrong foot (pun clearly intended).
Does this mean great golfers all had good footwork? Of course not. But I think those with poor footwork (usually the LPGA) start to rely more on their arms instead of their pivot to deliver the clubhead to the ball (also common on the LPGA). And when you do that, I believe you start relying more on hand and eye coordination to control the face, clubhead path and low point.
Let's take a look at Hogan's footwork.
Another great ballstriker, Moe Norman. Take a look at his footwork.
Now Moe is an interesting case because he 'flung' the arms off his chest at and thru impact, but I think it shows that good footwork can never be a bad thing.
