This isn't really a golf post, but since I got three emails today about the ball, the power game and it's effect on golf. All seemed were inspired by Wimbledon's efforts to try and reverse the same dreadful trend that has lessened all-around skill.
While golf now has a database of wear patterns (of sorts) via ShotLink since 2003, what better evidence of the change in tennis than this post (courtesy of reader Brian) from tennis fan and blogger Paul Kedrosky.
