Ever since the Hover thread was started I've been wondering about why I see most professional golfers ground their club before starting their golf swing. If sure there is a solid reason for it, I just can't figure out what it is. The only pro I can think of at the moment who doesn't ground his club before starting his swing is Jason Dufner. I'm sure there are many others, but in watching the PGA tournaments lately seems like many of the pros ground their clubs first.
