We went to watch the team today. Course is beautiful - but appears very difficult. I grabbed a scorecard... From the tips, the course is a Par 71, rated at 74.9 with a slope of 150. Factoring in all of the elevation changes, this course would be a bit*h. In comparison, TPC Sawgrass from the tips is a par 72 with a 76.4 rating and a slope of 155. From the "US Open" tees, Pebble is a par 71 with a 75.5 rating and a slope of 145.
Mix in the cold and rain that we had here on Monday & Tuesday (especially on Tuesday), and I can see how a team from Texas might struggle. (and I have no idea how USC played so well!)
