With the low temperatures, high wind, and sideways blowing rain this is an absolute nightmare for the players, caddies and fans. Players like to control as many variables as possible and in conditions like this you can throw your game plan out the window. You can't control anything. It is a helpless feeling. You have no sense of control and feel vulnerable to the elements. Add to that the extreme pressure of the Ryder Cup and the situation becomes magnified.
For the U.S. team there is another issue as well. Apparently the team rain suits are not waterproof and some of the players are not happy with the functionality of those rain suits. To the casual fan this may not seem like a big deal. I can assure you, as a former player, this can become a major issue. A properly functioning rain suit is essential on a day like this. You are battling your nerves, the golf course, and your opponent. You shouldn't be required to battle your equipment as well.
In a match that is projected to be as close as this year's Ryder Cup it would be sad to think that the outcome could ultimately be determined by an under performing piece of outer wear.
