If the average players were from Royal County Down or another club where the players were used to dealing with wind and high rough,they'd have a fair chance, but I'd doubt it unless they regularly played the back tees, which I doubt is allowed at RCD.
but 99% aren't used to difficult courses, to say nothing of the "ego" handicap factor.
and add in the 7600 yard course -giving them apmle opportunities to hit a second shot into the schmoo, even if their drive is successful.
