The fact that the fairways and greens were firmer than they have been in recent memory had much to do with the inflated driving distances this week. I don't believe that 17 at Riviera has been particularly reachable this week was because of the F&F conditions. I'm not accusing anone of trying to have it both ways, but having "proper" (that is to say, Firm/Fast) fairway conditions is bound to increase driving distances.
I see this shortening of golf courses in much the same way as I see the issue of Global Warming. Yes, it's a concern, but it is often overblown. I happen to believe that advances in physical training account for the distance increases. Back in the day, you had to be a big, "naturally strong" person in order to hit the ball a long way. Today, we have players like Camilo Villegas, Charles Howell III, and many others, who are rather slight of build but very long of drive.
The major fact, in my opinion, is that the biggest increase is not in how far the longest players hit the ball. Rather, it is in the percentage of players who hit the ball so far. Lest we forget, John Daly was hitting 340 yard drives (as at least a dozen Tour stars do now) in 1991. But, it wasn't deemed a problem because he was the only player who hit the ball so far. Now, a lot of people hit it that far, so the Tour has (unfortunately) serviced this happening by playing golf courses that favor the longest hitters. As we saw at Brown Deer Park last year, both shorter (Pavin) and longer (Lickliter) hitters had chances to win. The bombers don't overpower the better, shorter courses, but the pea-shooters have little advantage at the longer, more wide-open venues. This is why Shinnecock was so great a venue for the US Open in 2004, and why Merion will not be easy in 2013.
When Jim Furyk is #2 in the world, I don't believe we need to be in Panic Mode for the state of our sport, on the professional or amateur level.
Phew, there's my scatterbrained take on the ball-hysteria.
