David,
That is exactly what the USGA and Chambers Bay don't want people thinking!!!
There is nothing wrong with any of the green's current condition. It is ALL precautionary. After being so wet winter time a year ago, it ruined the greens well into May/June. It wasn't just a problem at Chambers.... Several local courses were working constantly to save the greens. This winter was predicted to be just as bad, but it turned out to be fairly mild. The greens are fine this year. Again, ALL precautionary. Apparently, March still has a chance of being poor weather wise. So, the temps continue. The USGA and Chambers Bay want the best for the best. Plus, the temps are placed along bunkers, run at the same speed, and are still fescue. If you weren't told they were temps, you might not even know. So, the USGA doesn't even feel bad about having temps. #15 is the only bummer because there isn't a spot for a temp.
