Kalen,
I think it was a design consideration.
The unfortunate thing about ANGC is the disconnect with AM.
Had there been a continuation of the relationship subsequent to opening day, the generous width might have been preserved and # 15 might have been a split fairway.
On the other hand, Maxwell's contribution seems to have been very positive.
Many, if not most believe that # 7 and # 10 were improved, and that # 16 was subsequently improved.
I happen to like the concept of a split fairway, especially if one side provides an advantage for the next shot at the expense of it being more difficult to get to, sort of like the "bottle" hole at NGLA.
And, I think the LEFT side would have been the preferred side due to the cant of the green and the angle of attack.
Remember, Ross did this at Seminole on a par 5 just a few years earlier, although the configuration of the holes are wildly different.
The very real dilema that ANGC faces is the difficulty or inability to serve two Masters, the members and guests and the annual Major, The Masters.
I don't know of any course that could accomodate routine play and a Major every year without alterations to the original golf course.
P.S.. I love the old fairway bunker on # 14
