What an idiotic redesign approach.
Essentially, ruin the 9th simply because they decided to make the 7th a par 5. From their proposal:
This hole could possibly remain a short par five which would suit the green, but the 7th becomes a par five, so on balance it is better to play as a par four to keep the par at 72 as it always has been.
What sense does it make to design this way? Some change might be needed due to nature, but why needlessly change something that works so well and is really unique? Their proposal does note that the 7-9 yardage (only back tee yardages listed, of course) stays the same in their redesign, as if this is some demonstration of effectiveness.
