When I walk down the range before an outing, I'll see 40 people banging drivers, warming up. And at least 30 of those players will have the same fundamental flaw in their setup: a ball position that's way too far back. It's an issue that starts a chain reaction of accuracy-wrecking, power-stealing swing mistakes. It kills your score, and worse, it wastes all the advantages those high-tech 460cc drivers have built into them. Trust me: If you're not breaking 90 and regularly hitting fairways, you aren't playing your ball far enough forward with the driver -- no matter how far up you think it is. Check out the sequences below to see why you need to play the ball off your left heel.
