Actually, we have several new courses in the D/FW metroplex designed by good, though less well known architects. Jeff Brauer, John Colligan, Keith Foster, and David Graham with Gary Panks have all done some fine work in this area.
The primary reason why well heeled developers flock to Nicklaus and Fazio is that these two gentlemen have an outstanding record of building courses that sell high priced memberships and lots. Whether you believe as I do that many people pay a premium for belonging to a Fazio or Nicklaus design because they tend to be superior golf properties, or you think that these folks are either snobs, stupid, or both, the hard fact is that these projects usually perform very well financially.
While Tom Doak and some of the other preferred architects of this site may be doing some very laudable work, they do not yet have the track record and name recognition which translates to $500,000 lots and $100,000 initiation fees.
In Tom's case, he seems to be getting plenty of work anyways. His Lubbock project, if it comes to fruition, will probably go further in identifying his talent than his work on Pacific Dunes. Here he will have a relatively unexciting canvass, but reportedly, sufficient budget to move a lot of dirt. If he is to make the Texas Tech U. course the top collegiate facility in the country (supposedly the benefactor's objective), he will probably have to go well beyond his minimalist instincts and apply some very bold strokes.
Finally, there are some of us with more than average knowledge of golf course architecture and the game of golf who actually have a lot of respect for the work of Jack Nicklaus and Tom Fazio. It is not incongruous to appreciate the classic designs of MacKenzie, Ross, Tillinghast, Raynor, Thomas, and MacDonald while enjoying the bold, modern style of Fazio, Nicklaus, Dye, and the Jones family.
