These guys are good. That's what they say about PGA tour players; and it's true. But where they are really good is on the greens. Bobby Jones, when assessing the next generation of top players, felt that it was on the greens that they were really better than players of his generation. Part of this had to do with better agronomy that allowed them to putt on better surfaces, but part of it was simply better putting.
Consider Rickie this week. After two days he is thirty for thirty putting from 10 feet and in. Thirty for thirty: I mean that is simply crazy good. When Dave Peltz did a study of tour pros he found that they made fifty percent of their putts from six feet. Rickie is one hundred percent from ten feet. That's not putting; that's magic.
