you obviously aren't a serious golfer, and obviously know nothing about golf courses, so you might want to post about something else.
A), i played the old course many times over 50 plus yrs, including in the past 10 yrs, and have seen it in great shape as well as poor shape over that span.
B), what shape it was in at any point in time has nothing to do with the layout itself, or what shape it could be in.
C), only the grossly ill informed or someone with an agenda would ever label a great design "outdated".
are Augusta, Pebble Beach, and the rest of the US's non Pete Dye esque golf course royalty also "outdated"?
the basic layout was flat great. the original architech didn't have 12 mil to work with.
yes, it needed sand, some water, (there wasn't a fairway trap or water feature on the entire course as built, but that's easily added), some lengthening due to modern equipment, (was plenty long pre equipment changes that made all great layouts need lengthening), modern irrigation, and premium grass.
had they just done that, IU would be the best course in the state, one of the premier courses in the midwest, and far nicer than what they now have.
