JS,
One of the problems that I see with Fazio ("Fabio") bashing is that what is being bashed is likely not the doings of the man but that of any number of prior architects, superintendents, green committees, head pros, influential members, etc. Fazio and other "name" architects may be simply renovating the existing course to make it "better" as defined by the decision makers at the club- the employers. A question which is not typically posed is if the "original" design was thought to be sufficient or acceptable, why was it changed. (I know, it is a bunch of know-nothing rich white guys who don't have anything better to do but to desecrate holy ground just running amuck!)
Regarding Bel-Air, I am unaware that it was ever considered to be in the same class as LACC-North or Riviera. I've only played it once, perhaps before "Fabio" came on board, and enjoyed my time there. I think both of the Fazio originals you mentioned and which I've played (not Oak Creek) are far superior courses, but I am much more a fan of modern gca than some here. And no, I am not on the evil one's retainer though I wouldn't mind.
I do look forward to some day getting back to LACC and seeing the restoration work of Hanse and Shackelford. Hopefully the economy will settle and the club will give a green light to the whole project. Who knows, maybe it will make such a strong statement that Riviera and Bel-Air may be moved to follow suit. Don't despair. Assuming that the California Coastal Commission is not involved, most anything that Fazio or anyone else has altered can be undone.
