Having seen hundreds of players hit and hold the left portion of #17 green, it has to be the firmness that's preventing the pros from finishing on the surface. That the entire green could be enlarged sympathetically by 25 percent and really better accommodate the pros (and everyone else.) If you look at older photos, the hole had a more expansive look and feel.
I will say the the prevailing NW wind really calls for a slight cut shot, held into that wind. The problem is that the tee box rarely has the markers over far enough left to hit that shot without difficulty. The straight or drawn ball has little chance of holding when that green is firm. It's that simple.
#14 for me is another story. Many on this site(and elsewhere) cried it was unfair during the most recent U. S. Open. Bullstinky! It was an AWESOME set-up. You had to understand the hole AND think. That reality destroyed much of the field. Sometimes you have to show restraint and accept that you will get punished if you are too aggressive. Except for a front right pin, which NEVER occurs in a professional event, long right is ALWAYS the miss on that hole. It leaves you full access to any other portion of the green, with plenty of surface to work with. Most importantly, you won't leave the green with your next shot unless you basically skull it.
Now to where that hole could be improved, from my view. That upper portion has room to enlarge and increase the pinnable area up there, particularly on the right. Where that hole certainly needs help is the washboard steep right front and central portions. The blasted sand from the right parallel bunker landing on the green over the years has SIGNIFICANTLY increased the pitch angle of the slope. They need to totally redo that and soften the steepness. Done deftly, this would allow more opportunity to pin a location in that area. The firmness and speed of both 14 and #17 could be kept a tad less than the other holes during a professiona event and I believe much of the consternation about them would disappear.
