It's important to set the record straight -- there are times when the big boys do hit a mid-iron 230 or more yards WHEN conditions permit or they are favorable. HOWEVER --
the 17th at Olympia Fields, among other holes of this type, have required the world's best to hit long irons and even woods into them. Let me also point out that holes of this are needed because too often that part of a golfer's game (at that level) is rarely tested in the throes of high level competition.
SPDB:
You're right -- the short par-3 does have a place. But, unless such a hole features a daily possibility of wind bursts (i.e. 7th at PB, 12th at ANGC, to name just two) or has some unique setting / green configuration, these type of holes are really easy prey for the big name players.
