Interesting article.
The only thing I can think of is growing the rough another 4 inches and narrowing the fairways. They can't make the greens any faster than they already are, otherwise the wind would certainly be a problem with the ball moving. They can't add much more length to the current rotation of courses. Shortening the course without reeling back the equipment won't change the current style of play. And I really don't foresee a time anytime soon when the USGA and R&A will regulate the ball.
We hear the fallout all the time when a course gets slaughtered, but few are talking about the monsoon-like weather they've had the past week there that played a huge role in scoring.
Let the fairways get a little growth, reducing rollout. Let the rough grow nice and thick. There is no real consequence for missing a fairway, so change that. If these guys are having to swing as hard as they can at a ball they can barely see, direction will become a serious problem.
This isn't that complicated. No consequences for missing a fairway = what is happening. And if they find the narrower fairways with 115 mph of club head speed, they deserve to be rewarded, no?
