I would hope people would highlight two different aspects into the discussion -- total distance versus the ability to carry the ball.
When you get "hot" fairways on the PGA Tour the total amount of distance achieved is somewhat stretched. I don't doubt many PGA tour players can carry the ball 260-265 yards in the air -- but ask them to do that at say 275-285 yards and I believe the field narrows considerably.
Just check out total driving distance stats and I think you'll find that carrying the ball is the real test of power because turf conditions can be so different and sometimes very beneficial. Case in point -- the distance Ernie Els was getting at the Mercedes Champiosnhips at Kapulua.
No doubt the distance that strong players are getting is increasing but to think that "everyone" is doing it is a bit much. Measure distance at sea level and when wind and turf are nonfactors. I don't doubt that the very top can do all the distance gain so many talk about -- but those numbers are not as great as many might think.
By the way I have also covered a full range of PGA Tour, Senior Tour (Champions) and LPGA events over the last 25 years so I view these things through personal observation as well.
