I contend that we continue to underestimate how good today's professional player really is. They absolutely pillage any course under 6500 yards with anything short of a contrived set-up.
Bogey
Then how do you explain Rose not breaking par at New Zealand GC, which is about 6000 yards? Having putted the greens last week, they are true but nowhere near tour pace - the perfect combination for making plenty of putts. If it was purely about distance, he should have torn it a new arsehole.
I guess it depends on how you define pillage. One of the misleading factors is there is a lower bound to scoring, but no upper bound. You can put a tour pro on the easiest 6000 yard LPGA course and they're probably not going to shoot 60. Someone posted an interesting article about a year, maybe 2 years, ago about Steve Marino joining a Maryland sportswriter at his (the sportswriter's) home muni. The writer asked Marino what he thought he'd shoot; Marino replied something like low 60s, maybe even flirting with high 50s. He ended up shooting 68, if I recall correctly. I'll have to see if I can find the article.
