I've not played any, but it sounds like all must rate pretty high to damn high. Anyone willing to get specific? Is Pacific Dunes a 10? Cape Kidnappers? What about the rest of his courses? Any fives or sixes, or less, in the mix?
The ones that are nearly finished, and open soon, should be open to discussion, too.
On a related note, the Doak scale gives us a numerical way to compare architects. One example: take the top ten courses by Mac, Tillie, Colt, Doak, Dye, Ross, etc, as measured by the Doak scale. Average them. See how they measure up against each other.
This would be one way to mathematically test the proposition made recently in another thread that Tillie is the greatest architect of all.
