Just get it started on the right line. It'll stay there. I remember something in one of Harvey's books, wholly unscientific, of course, that on shorter putts we ought to concern ourselves with line where on longer putts we should concentrate on speed. That's exactly right. When you're taking a putt of over, say, fifteen or twenty feet, there's just no way on earth that you can read it completely accurately because of the footprints, the spikemarks, the different undulations in the green.
Speed controls the line that a ball rolls on.
Golfers don't realize. And it could be, and it usually is, the fact not that you pushed or pulled it, but that you didn't hard enough, or you hit it too hard. I've measured that eight out of ten putts that miss the hole could've gone in if they'd have been rolled the right speed. Eight out of ten putts could've gone in if they'd been rolled the right speed. In other words, they were on a good enough line that they could've made the hole.
