Taken in the bigger context, while the PGA has been villified over the years for taking their championship to some "questionable" venues, in reality, they made a conscious decision years ago to try to bring new courses into the major rotation, when the USGA seemed stuck on a dozen or so, the Masters on one, and the British Open on 7. We should give them Kudos for that, or golf would have been stuck in an awful rut.
The Masters will never move of course, and the USGA seems to be branching out on its own using newer courses, perhaps seeing some of the success the PGA did have? It is sort of like Mcdonalds vs the local restaurants - you know what you get with the old standbys, and it can go either way trying some place new (to you).
At any rate, the PGA would seemingly get some credit for newer courses being used more often. And, they need to, although maybe Merion in 2013 will show that the shorter old courses can still hold the majors without the major challenge being bending shots around 200 yard dogleg points, like WF.
Not sure what AAC and Bradley's win means about the relationship between winners and venues. It still seems rather random and any kind of winner (crowd fave, grizzled vet, rookie, unknown) could probably win at any time. It did occur to me that the PGA might have meant more to a Bradley, from a PGA family, than it did to some tour pros who view the PGA as the fourth most important major, regardless of the venue, and that may have inspired his great play.
