Matt:
I've never thought Castle Pines was one of Jack's best courses, or one of the best courses in the country ... I thought it was on there more as a token representative for Colorado. But, it doesn't have to be replaced with a different token, does it? It could just as easily be replaced with Sutton Bay, or Black Mesa, or Rolling Green or Eastward Ho or The Bridge, although the last now seems unlikely.
"The cutting edge" is not necessarily indicative of the best work in the country.
