Increasing Athleticism! Then How Are Geezers Picking Up Yards?

With the tour in town I haven't had a chance to read the USGA/R&A distance report, so I'm relying on Mike Stachura's take at GolfDigest.com. It's fascinating to see that those suggesting distances are changing were labeled distance "truthers", implying a conspiratorial element.

That description is even more peculiar given this:

To clarify, the PGA Tour driving distance average has grown by 2.8 yards from 2013-’16, or 0.7 yards per year. In that same time frame, the PGA Tour Champions has seen a 5.7-yard increase, or nearly 1.5 yards per year, while the Web.com Tour is up 2.1 yards since 2013, or better than half-a-yard per year.

So the not-flatbellies of the PGA Tour Champions have picked up five yards in four seasons--once an eye-opening number--yet we are to believe athleticism is driving many increases as opposed to the manufacturers and Trackman out-maneuvering the governing bodies?

The Distance Report specifically breaks down distance into several groups, including the percentage of 300-yard drives as tracked by the European Tour and PGA Tour. Most notable is how the PGA Tour with 31.2 percent of its drives longer than 300 yards in 2016 shows nearly a 17-percent increase since 2003.

When the 2003 Joint Statement of Principles was issued by the organizations it discussed the skill word, the significant word and the statement did not care what caused increases. A 17 percent increase is, apparently, not significant.

As well, the number of players averaging more than 300 yards for the season has increased. In 2003, that number was nine. That figure was 13 in 2008, 21 in 2011 and 25 in 2014. By 2016, it had tripled to 27. This year’s number (38) is actually about 20 percent fewer than a year ago (47).

But back to increasing athleticism. From the USGA's John Spitzer:

“We do not have a trigger and there’s no contemplation of one, but clearly even if you look at this slow creep of one foot a year and attributed that to athleticism, in 20 years you’re going to have a seven-yard increase,” he said. “Athleticism is still going to increase and at some point it may need to be addressed, just not as an equipment issue but as a pure distance issue long term.”

How did the Joint Statement of Principles fail to address the long term?
