A couple Langford courses come to mind.
I'm not as in love with Spring Valley as some, but it certainly has the bones of what could be a very good golf course. It might be a 3 or 4 on the Doak Scale today, and I don't know if it would even rank that high on the average rater's 1-10 scale. I could imagine a reno/resto that puts sand in bunkers, recaptures and enhances the bold shaping, recaptures the green pads, thins some trees, and peels back some of the layers that currently keep the course from shining. But I don't think the routing or the property holds up to say, Lawsonia. Hard for me to see it becoming anything better than a 6 or 7. But it could be a 6 or 7 that sparks a lot of salivating reactions from Woke Golf Instagram.
Clovernook is near and dear to my heart, and I've seen the original routing map. It's already a good course - I'd probably give it a 5. Thin some trees, recapture some of the bold bunker shaping, build the bunkers that were originally on the map but never built on the course, and establish the giant shared fairway between 17, 18, and 10 from that original routing map, and you might have... well, another 6 or 7 that gets a LOT of Instagram love.
Thinking about it in the inverse - what if Crystal Downs had gone the way of pre-restoration Lookout Mountain post-Great Depression? Greens mowed in dull circles and reduced in size by 50%, bunkers abandoned, rough allowed to overgrow, maybe a few trees slapped around the property. Could poor maintenance and neglect conceivably have bastardized the course to such a degree that its greatness was no longer recognizable? It seems like a good example of a course that:
A. Is utterly awesome
B. Lacks the ocean views and other peripheral pizzazz that inspires Instagramming even when the architecture isn't shining
C. Has features so bold that, if neglected, they could become completely wonky. Like, what even is the 7th hole if the green pad shrunk to a circle right at the crook of the L? Or the 5th hole if the Three Sisters were grassed over and the fairway narrowed and turned into a simple dogleg left? 11 playing to a round green that sends every putt from above the hole rolling off the green?
I guess it's feasible to me that there could be a course somewhere out there with 9-10 potential, but in such an extreme state of neglect that most of us would see it as a 4 or so in current state. But it's pretty unlikely based on any actual examples I can think of.
What would you rate Southern Pines today, and how good could it be with a great renovation effort?
