Garland,
There are more than a few situations where the ability to carry X bunker or ridge will provide you with a real chance at hitting a par 5 in two or an ideal line into the green. On other holes, ball placement on a particular side of the fairway, like on 13 where you want to stay right of the bunker in the middle of the fairway, is important to provide the best approach to the pin.
The ability to hit accurate irons is certainly important as well. Which, like you said, seems to be standard on Nicklaus courses.
Overall, the course is playable for any golfer because there is reasonable width, but a drive on the wrong side of the fairway or in the rough will leave a tough shot at the green or force a layup.
