Matt,
I understand these are world class players. But using this same logic, couldn't one also say they should have the ability/skills to keep the ball out of the rough?
What I'm really getting at here, is that so many here seem to get thier knickers in a wad with too much rough and the players being penalized by having to chip out. Yet missing the green by a mere few inches could be the difference between a ball on the green and a ball in the water? Which is the worse or more arbitrary penalty?
Tom D alluded to this during the Open at Oakmont. I can't remember which hole it was, but many were complaining that getting into a certain greenside bunker was too brutal, because the green sloped away from them on the recovery shot. Yet if it had been a pond there, no one would have thought that a big deal. Even though they are both hazards, at least from a bunker you have a chance to recover.
I view this issue in the same context as that. At least when one goes in the rough they still have a chance. Hit it in the water on 12 and you're looking at guranteed bogey, likely double bogey.
