I wasn't around for the opens last year.
I will predict the following:
Oakmont 68 hard to believe that a huge number of people can shoot under that score with the green speed that we are using.
St Andrews 66 while I know as SP said many more people have played this course I still think that with the back tees and the green speed, it will not be possible to blow out the low numbers on STA although I did shoot 30 on the front while ago.
