"It has a little bit to do with the ball."

In Doug Ferguson's account of Tiger's switch to a slightly harder cover in preparation for the Open Championship, it is suggested that his improved driving distance is a combination of ball and improved mechanics.

"The more I keep playing, the better I get," Woods said Saturday after recovering from an atrocious start to shoot even-par 70, making up little ground in the AT&T National. "It has a little bit to do with the ball."

Woods still uses a One Tour, this ball marked with a star symbol between the two words. He started using it this week at Aronimink, most likely as part of his preparations for the British Open in two weeks at St. Andrews, where the wind is often a major factor.

The world's No. 1 player often has talked about how he uses one of the softest golf balls on tour, which gives him greater control around the greens. This version would be helpful in windy conditions because it spins less.

This is the real eye-opener:

Once among the longest hitters in golf, Woods was 21st in driving distance last year. Going into the AT&T National, he was ranked 78th based on two measured drives per round. Through two rounds on a fast, firm Aronimink course, Woods was leading the tournament in driving distance at just over 328 yards.

His additional length was most evident during the second round, when he was playing with Dustin Johnson. On consecutive holes, Woods hit one drive 26 yards past Johnson, and another 10 yards past him. Both led to birdies.

So, we've heard all of these years that the ball is not the real reason for distance gains over the last decade. And we've been told that rolling back the Overall Distance Standard via new ball rules would be complicated and in general, not feasible. Yet here we have Tiger switching balls (and perhaps improving his swing), but we are seeing a serious difference in his driving distance with a simple switch.

Why can't we contemplate a future with a ball that has the characteristics of the pellet Tiger's been using?  A little spinnier, but sharing many of the components that make the modern ball last longer?
