With the Amateur approaching, I have seen a couple of articles that imply that Oakmont might be vulnerable based on how far some of the players now hit it.
As Oakmont is one of those classic courses that gets harder and harder (!) as one nears the green, monster drives simply don't render the course helpless. Far from it.
Typically, these monster 350 yard driver guys aren't able to hit in 'dead' approach shots that won't spin wildly away on these sloped greens. In general, the bigger the driver, the more spin they put on the ball with their irons as well. Guys like Tiger don't develop the knuckleball approach until later into their professional career, if ever. Thus, who cares how far someone might drive it on the downhill 1st? Good luck getting the approach close.
Still, a lot has changed in the past 25 years including how many great golf courses people get to play. Not to long ago, a contestant in the Am might never have played on greens faster than 11 on the stimp for instance. These days, it takes a lot to freak out the best Am players as they have had the opportunity to see lake-lined holes, ultra fast greens, etc.
However, I contend that Oakmont is that extra notch (or two) above what 99% of them will have ever experienced (like its front to back greens). Just imagine a contestant's first encounter with the 1st green at Oakmont?!
Once the greens get these guys thinking (be it during the practice rounds, stroke play, or well into the match play rounds), and once they understand the immense pressure to be in the fairway, advantage will shift irrevocably to Fownes's great design.
Oakmont will make for fascinating TV viewing, especially with J. Miller in the booth calling it as he sees it.
Cheers,
