I think at least one will break 100 and probably more. If they simply try to break 100, then they have a good shot. If they get greedy and try to shoot 85, then they could shoot 110.
We got to play Quail Hollow the morning after the tournament a couple of years ago, before they cut the rough or moved the pins or anything. Granted, that is not quite a US Open setup, but the winning score of 277 was not far from what the Open produces. Also, it was soaking wet and 7400 yards and the rough was impossible that year. Anyway, everyone was between a 6 and an 11 hdcp and nobody broke 90, BUT nobody came close to going over 100 either. It was just a bogey slog with an occasional double or triple and an occasional lucky par. Everyone gravitated around 92 or so when it was all said and done (including the guy who magically birdied 1, 2 and 7).
Each Open is different and I doubt any normal 10 could break 100 at Oakmont or that crazy setup at Shinnecock, but I think they have a shot at Torrey. We will see.
