et. al.,
Hale Irwin was an All Conference defensive back at Colorado.
I don't know any current players who bring those athletic credentials with them, so the contention that today's players are more athletic, or in better shape, seems like a dubious argument.
In addition, Greg Norman in his prime was lean, mean and fit, yet, on # 18 at ANGC he hit a 4-iron wide right, which cost him the Masters. Only a few years later, less fit, less athletic golfers were hitting sand wedge into the same green.
The hole has been lengthened by about 60 yards, and yet, PGA Tour pros are hitting medium irons, uphill, to that green.
When Palmer, Player and others used to hit 3-woods into # 15 and guys started hitting sandwedge a few years ago, you have to believe that the reason didn't lie within the realm of athleticism or being in shape.
Noone was fitter than Gary Player.
JES II,
It's the trajectory of the ball that renders the greens defenseless. A 170 yard 9-iron comes down like a butterfly with burnt feet, as opposed to the flight of an old 5-iron from that distance.
Not long ago I was forced to hit 2-irons from 170 yards and believe me, the architectural features and strategy take on heightened significance when the flight of the ball is low.
How many PGA Tour pros would play to a redan by hitting short of the green ?
Like the Maginot Line, architectural features are becoming obsolete, even for amateurs.
Even GREAT courses like Garden City Golf Club are seriously considering adding additional length to combat the inroads made against the golf course by hi-tech, and that's just for amateurs.
Club after club has done the same thing and the PGA Tour isn't stopping at any of those clubs.
