Without putting words in Joe's mouth, I saw two questions prior to his reply:
First question: "Any idea why they chose the courses that they did to host the matches?"
From the blog: "As for how the courses are going to play, one word comes to mind: long".
That doesn't necessarily mean that's the reason they chose those two courses, and there are certainly back tees at each course that are not figured into the yardage that mortals like us play, but BT and OM are the two longest courses from the back tees per the scorecards.
Second question: "Are you going to be caddying during the tournament?"
Pretty clear from the blog.
