Yale 16 is a great example of Wethered & Simpson's point. It's a needed breather before two brutes. And while 17 is less of a brute due to modern equipment (but a 4 still is hard earned), modern equipment has turned 16 into a reachable par 5. As Tim notes, Ramsay's expansion of the green has given support to reachability (and increased the probability of 3-putts
).
And why does reachable matter? Because of 17 and 18. Our breather hole gives us the "opportunity" to think about 17 & 18 while we're playing it, changing not only the quality of our play on 16, potentially, but the strategy we take. Nature abhors a vacuum and golfers fill pauses with...thoughts.
All this said, I'd be in favor of restoring the original green, just because I'd like to see it.
