Matt,
It is easy to throw out the relevance of the back tees, as long as you are also willing ton throw out the relevance of the course for the 1 to 3 percent of players who should really be playing the tips. Obviously, that's impossible form you, but it is really NOT NEARLY as difficult for others as you imagine.
For example, if I want to throw out that population of golfers, Winged Foot West is still the same ... an unrelenting test of accuracy in driving and iron play. Oakmont is still unrelentingly difficult due to its tilted and super fast greens. Bethpage Black, on the other hand, does not stand up as well architecturally if you stop worrying about the back tees.
The interesting part is that when you throw out the back tees, you can see clearly that some 6300 yard courses are clearly more interesting than your vaunted championship courses played from the same yardage. And the fact that the rankings fail to take that into account, because they are clearly all dominated by the view from the back tees, is somewhat sad. The place I noticed it the most was in looking through ballots from the few women who were on the GOLF Magazine panel ... their perspective was radically different, because they are not even looking at the back tees.
