Very cool article. I played Cobbs Creek on Walker Cup weekend this fall. Many of the greens (I am thinking of 2, 12, and 18) compare well with the lay-of-the-land greens at Merion's 4th and 5th holes.
Unfortunately the routing at Cobbs has changed since the original construction. As a result, the tee for the 12th hole was relocated, and the hole is much different now. The green is now used for the short par three sixth. How much work would be needed to relocate the tee to the current 14th tee? It would mean shortening the 7th hole, but from what I gather the 7th (originally the 9th hole) was a short par four to begin with.
Also unfortunate is the loss of the old par-five 13th. It looks the second shot across Cobbs Creek was very strategic and thrilling. Unlike the old 12th, this hole will not be restored unless the city buys back the driving range next store.
Fortunately, Cobbs Creek 3rd-5th holes still make fantastic use of the creek. 3 and 5 are both excellent, albeit overgrown, short par fours.
Along with the 3rd, my two favorites on the course are the current 12th (originally the 7th), and the 18th. The 12th is a great long par four to redan-style greensite. The 18th is a very unique finishing hole, with a green that is wicked at any speed.
