Sean:
I don't know who exactly is scoring each architect's performance on each project, other than the great architect in the sky.
But, if you insist on scoring, then I think you have to take credit away for eyesores, etc. No, it's not my fault if there is a power line running across the site, but just like an oceanfront, I have the power to determine how it's presented on the golf course. Certainly, some things are almost impossible to overcome, just like a Pacific Ocean view is difficult to screw up ... but you've got to take the bad with the good, or not take them at all.
There are other things which the architect might say he had no control over -- decisions he wants to pass off to the client, the shapers, the contractor, the engineers, town regulations, the Tour pro co-designer, ad nauseum -- but if he's not giving them all some credit, too, then pay no attention.
