I haven't chimed in on here in a while, but I think Jason Day has a point to his comments. I'm not entirely sure how to express my point either, but I regularly think about this in regards to design. During the dark ages, everything was longer, tighter, more penal, more difficult. To the point that courses like Oakland Hills (and many others) were being lengthen, trees planted, made tighter. Less fun overall. Of course manufacturers were going to come up with solutions to be able to hit it straighter and farther.
Let's say that design age never happened. Let's say no one was concerned with that and instead width and fun was being celebrated. Instead of ruin-ovations like Oakland Hills or the Jones family style in general, what if courses like Pacific Dunes or Sweetens Cove or even classic design like British courses or NGLA were built?
Would length be the ultimate battle? Would have designers like Nicklaus and Palmer and the Jones family have been celebrated or derided? What direction would manufacturers have directed their equipment R&D if courses couldn't be overpowered and instead needed placement and thought to succeed?
