Your friend is mistaken. The 13th hole at my home course, designed by Bob Cupp has such a bunker inside the right fairway line about 360 yards out on a 425 yard hole. It has a relatively high lip that gives it a green-side appearance from the right half of the fairway. It is made more effective by the fact that the green is canted from 8:00 to 2:00 and is slightly elevated. The result is that a lot of pitches get played from the fairway depression short-right for the third shot.
