It's a hard comparison to make, isn't it? When you do more courses (MANY more courses!) like Fazio has, you will have a lot of successes with an impressive "best of" list, but you are also likely to have more work about which there are questions. And so it is with Fazio.
There was a time when I joined in on the Fazio bashing that can break out here; I've softened at least somewhat. I still find a lot of what he does with bunkers to be objectionable, but I've also played a number of his courses that I like pretty well.
Since I mentioned bunkering, two stories, one familiar to many here, one not.
1. When Pinehurst #4 reopens this fall, the primary work that will have been done, beyond regrassing the greens, is the removal of 140 Fazio bunkers. Like many here, I think I see adding 140 bunkers to 18 holes of Ross as painting a mustache on the Mona Lisa.
2. In an interclub match this past Sunday at Hasentree in Wake Forest, NC, which is a Fazio "signature" that I like a lot, I watched one of my opponents, who played college golf and is still just excellent, take three to get out out of a fairway bunker and make double on the first hole. That hole is a 428 yd. dogleg par 4 and the #1 handicap hole; he played the rest of the round 2 over and shot 75. (And waxed us!)
I don't believe that years down the road we will EVER see anybody have to remove a significant number of bunkers from work that Doak or C&C did, nor do I believe that either of those would defend a green with an absurdly deep bunker almost 200 yards out. And that may be the difference in the three.
Nolan Ryan struck out 2500 more batters than did Greg Maddux, which is impressive. Of course, Ryan also walked 1800 more batters than Maddux did. You take the good with the bad; more volume means more of both.
