Rich -
When TOC was expanded on the right side of the outward nine circa 1870, there was a sense that those holes had become too wide and uninteresting. Low (Fowler also seems to have been involved) and others in the winter of 1904/5 built additional bunkers on the right sides of those holes.
Low added not just the two bunkers that are within 100 yards of the 2nd green but also several farther back on the right side of the fw. The bunkers were placed on the side from which a good player would want to approach the 2nd green. If those bunkers were successfully negotiated, an easier green entrance from the right was your reward. That is, the surrounds on the right side of the 2nd are supposed to be benign. One aspect of why so many architects down through time have thought it was a great hole.
By moving bunkers up against the green on the right as Dawson and his architectural toadies are doing is to eviscerate what Low was seeking to accomplish. Bunkers tightly against the right side of the green have the consequence of diminishing any advantage from approaching from that side. Which is a downgrade of the quality of the hole. It takes off the table its key playing strategy. Indeed, the very strategy that has made it such a notable hole over the years is, effectively, now gone. For normal punters like us the hole is now about hitting straight shots down the middle.
I reject out of hand any counter arguments about how pros now play the hole. There are vanishing few holes anywhere in the world where pros pause to consider best angles. So that is not, nor should it ever be, a basis for changes to the 2nd or any other hole of historic significance. And the 2nd at TOC was - until just this week - a hole of considerable historical significance.

P.S. I would argue (and have) that the design principles Low used in placing bunkers on TOC in 1904/5 is one of the early signs of a theory of golf design that we would call today 'strategic golf architecture'. But that's a bigger story for another day.
