Jordan:
That hole might have been best in the mid-1970's, when it wasn't there at all.
Medinah No. 3 always had two par-3's playing straight across the lake -- the second hole, with the green right down to the water's edge, and what is now the 13th, a long par-3 with the green set back up the hill a ways, which was then no. 17.
When the USGA told the club they HAD to build a new 18th hole if they ever wanted to host the US Open again, the entire back nine was re-routed, and the new 17th added, so that there were three par-3's over the lake. And they've been tinkering with it ever since.
To me, the only way they could have made the par-3 and given it more variety would have been to make it play on a diagonal over the water. Going straight across, no matter what they did, it was going to be too similar to one of the other two holes.
