I might suggest that instead of looking at data surrounding driving distance, we should consider distances achieved using iron shots. However much, or little, the USGA and the R&A claim driving distances have changed since 2007, there is no doubt whatsoever that 180 yard 8 irons and 220 yard 6 irons are a new found phenomena. If a hole is 500 yards and the tee shot is 290. what player is intimidated by the remaining 210 if that is a 6 or 7 iron? There was a time ( maybe 10-15 years ago) when only John Daly would attempt a 260 yard carry with a 2 iron. Today, many tour players attempt that shot routinely and some even use less club. On tour, most par fives have become medium to long par 4's. Like the popular, but ridiculously simple, "slam dunk" of the NBA, the fans and the sponsors love the par 5 hit in 2 and the subsequent eagle attempt. Fans who struggle at this most difficult game, marvel at the play of the pros and the distances they achieve. Let's not forget that the PGA Tour is in the entertainment business and to understand the undermining of the foundational principals of golf architecture seen through unrestrained distance technology, by both the PGA Tour and equipment companies, one must simply "follow the money."
