2. Leave a mark
"I like to raise my left heel in my backswing. This isn't a fashionable move, but I'd rather copy the likes of Hogan and Nicklaus than follow the swing fad du jour. On my downswing, I replant my heel and dig it in to establish a firm left side that I can turn hard against. When I'm hitting it good, I'll leave a single, noticeable footprint in the ground."
