"Wouldn't it be fun if the possibility really existed that Tiger might have hit his approach out of the light rough on the 72nd hole of the U.S. Open over the green?"

I'm still collecting my thoughts on the groove announcement (hey, I've only had a year). But Bug and Gnat over at GolfDigest.com chime in with a couple of questions that have been, uh, bugging me too, though maybe for different reasons. First, Bug (E. Michael Johnson):

How are they going to enforce this rule and what happens if it doesn't have the desired effect of restoring accuracy as an important part of the pro game?

There is a very good chance this will only have a minor impact, which gets us back to the ball study. Which I'm sure is moving right along.

And enforcement wise, I suspect the USGA testing department gurus have developed an easy way to test. I hope.

Then Gnat (Mike Stachura) asks:

Wouldn't it be fun if the possibility really existed that Tiger might have hit his approach out of the light rough on the 72nd hole of the U.S. Open over the green?

Actually no, and it was something I contemplated while standing there watching Tiger lined up that now famous birdie putt. I wondered how much his shot spinning back was influenced by grooves and how much was the result of his swing speed and personal Nike ball. I hope for future viewing interest the grooves played no role, because even the governing bodies must know that the backspin he imparted on that ball helped make for one of the great moments in golf history.
