Brent,
Interesting perspective. I'm not sure I ever thought of the effect our own assumptions have on how we approach an activity but it certainly seems it would be significant.
This anecdote should support your side.
I grew up playing golf on a good, hard golf course designed by William Flynn in the late 1920's. It is widely known that ball striking is a premium there and I became a pretty good ball striker. I also was a bit of a purist in the sense that I have always played forged irons and my on course approach was to try and hit the "proper" shot all the time, eg. I would always try to shape the ball into the pin the way Hogan spoke about it, high, low, right-to-left and left-to-right.
At the point where I felt my game was worthy of trying to earn a living on I turned pro, moved to Florida and played minitours, Monday qualifiers and Q-school for three years. With not enough success to live on I stopped playing and got a real job. The first time someone asked me what about my game was lacking as compared to those that succeeded at my level and moved on to one of the two real Tours (PGA or Nationwide) The first thing that came to mind was ball striking to the extent that those guys were real good at hitting one shot all the time and very rarely hit any other shots. In other words, they would have their standard shot and they knew what the ball was going to do. Whether it was a fade, a draw, high or low they hit that shot all the time and never thought about "the proper shot" for the circumstance.
My assumption that hitting all the different shots at the appropriate time would be better than hitting one shot all the time is the one change I would make if I were to go back and start over.
More to your point about players now understanding that they can play at least as well from the rough as the fairway so long as there is a sustantial distance advantage, do you think the increased length off the tee (therefore reduced distance into the green) today versus 1975 which turns the second shot into a wedge as opposed to a 7 iron for this shot out of the rough is a contributor to this change of approach? Or put another way, 30 years ago if a player sacrificed accuracy for an additional 25 yards they were still hitting an approach club (out of the rough) that was difficult to control, whereas today players are sacrificing an 8iron out of the fairway for a wedge out of the rough. I think the basis for the FLOGGERS position is that they are hitting wedges into the greens so why sacrifice the distance.
