I thought this was an amazingly well written and insightful article. I decided to just repost it, as a quote - instead of butchering it!

June 23, 2009 -- You will see all kinds of numbers and statistics centered around this past week, but in my opinion, this year's U.S. Open was won with a driver. Lucas Glover proved, once again, how critical driving is to winning major championships. Lucas was No. 1 on tour all year in total driving and this week at the 7,400-yard Beth Page Black course, he was first in the field. Total driving considers both distance and direction and Lucas is currently the master. There are some key lessons that you can learn from Lucas's driving game.
First, Lucas had great posture. When most golfers think of posture they envision a straight back and a good bend from the hips. There is another part of posture that is widely unknown, spine tilt. If you look at Lucas Glover's set up from face on, you will notice that his right hip and shoulder were lower than the left. The players on tour who drive it the farthest hit up on the ball and tilting away from the target at address, encourages this.
Second, Lucas kept his swing under control and made very solid contact. Clubhead speed produces distance, however solid contact cannot be overlooked. Although Lucas hit the ball hard, he never swung at 100-percent speed. As a result he was able to stay in balance and make consistently solid contact. I call this the "85-percent rule." Unless you absolutely have to rip it, you should always leave a little in the bag, to consistently hit the center of the club face.
Third, Lucas hit the same shot off the tee every time. Whether he was on a dog leg left or right, he played his draw. For most players it is easier to play the same shot pattern, rather than try to work it both ways. Whether you draw it or fade it, try to hit the same shot every time, and you will drive it more consistently.
Learn from Lucas Glover's awesome driving performance at the U.S. Open and make your driver one of the best clubs in your bag. Driving sets up the hole and gives you an opportunity to score. Working on driving it longer and straighter may not produce a U.S. Open victory, but you will have a heck of a lot more fun and shoot lower scores.
