Craig -
I like Brian's synopsis, but I'll expand just a touch.
Quite a few people (read: raters
) felt that RC was not nearly demanding enough off the tee to warrant discussion as a great course. There was a very interesting thread that developed - if you could ignore the vitriol - about if RC was a top 10 modern course from 50 yards and in and a top 1000 course from the tee. I didn't agree with it - in fact, it was in many ways the impetus for my own thoughts regarding subtlety in gca - but it was pretty interesting.
For those who'd care to search, I'm pretty certain the primary thread in question was started by Tim Weiman in response to a comment made by David Wigler. Ignore the fact that people took comments a little too personally and you'll see an interesting discussion of the course's merits, as well as insight into each participants' philosophy of gca.
A certain long hitting NJ gca-er
also seemed to feel RC was not demanding enough off the tee, although he did praise the course a great deal for its merits. There's probably a thread started by him from a couple years ago.
There is also a matchplay thread with RC versus Wild Horse, which discussed each courses' merits fairly well.
