Jeff, Steve Smyers could well be right, based only on what he said. And what he said is that "the game" has been "changed" by agronomy.
And of course he is right, just as Bob Jones was right when he suggested that the biggest equipment change in his lifetime was the modern greens-mower.
Where I depart from Steve Smyers (and I would be my profound honor to debate/discuss this with Mr. Smyers) is on the notion of whether the golf ball is to "blame" for distance advances in the Pro V era, and whether, if the golf ball is not solely "to blame," whether anything should be done about it.
It seems simple to me; if there is widespread opposition to making some golf clubs illegal ex post facto, and if modern agronomy techniques make golf courses more beautiful, fairer and more fun, and if big, strong, healthy well-caoched kids can hit golf balls farther than ever... Well, that leaves the golf ball.
One of my few gripes with Steve Smyers on the "agronomy" topic is whether agronomy techniques are being used, not to make courses better, but whether they are being used to "trick" the architecture and scoring. We all understand the phenomenon in which greens speeds at Ross and Mackenzie designs are extremely elevated so as to protect scoring, with the side effect of making half the hole locations unusable. And I understand the concept (dubious it may be) that fairways can be cut to such a low height as to make them as "fast" as greens. And how irrigation has changed everything. I understand all of that. Assuredly, Steve Smyers understands it better than I ever will.
What I come back to is any statement from Mr. Smyers that appears to be a provocation to the golf-ball-rollback proponents. Perhaps, there is a context to it. Perhaps, Steve Smyers, USGA Man, has heard his fill of complaints about how the USGA has done nothing about technologically-produced distance. If he has heard his fill of that, I'd suggest that it is deserved.
