As Howard said, the fescue is being cut back.

You have 156 of the best players in the world. If you can't hit it in that avenue, you might as well pack your bags and go home. Like, I don't get... These are the widest fairways we have ever played in the US Open, and the first and second cut is another 10 yards on top of that.... This is the US Open. It is supposed to the hardest test. If guys can't put it play in a 50 yard zone, they don't have much to complain about."
My theory:
1. The USGA is fighting an uphill battle after the last two years. They don't need more controversy (even though it is stupid and will be seen as soft cause the fairways are so wide).
2. Rain last night. Rain this morning. Rain forecasted as a possibility Wednesday night, and a 50-50 Friday night through Sunday afternoon. The fescue is only going to be thicker. The fairways will probably have lost some heat. The course will play long, so the USGA might think the course playing longer adds enough difficulty by making the players hit driver on every hole (?)
