I do agree with much of what Michael says here, I slightly disagree with the premise of this thread. While I hate to see long and thick rough (especially around the greens), I don't think it totally eliminates options on this particular course for the professional.
TPC has so many doglegs and hazards, that a layup is fairly tricky. Plus, some holes may have options enhanced if a player hits it in the rough. In particular, I'm thinking about #4 and #11. For #4, the player will have a short iron in no matter where he hits the tee shot. If he hits in the rough, he can surely reach the green. I see 3 options: hack out 50 yards short of the creek (most do not take this option BTW), play at the green with their 120 yd club and risk the water and bounding over, or playing over the creek but right of the green (there is some fairway there) leaving an easy pitch.
There are similar options out of the rough on #11.
Let's face it, the pros are so good that they usually take the aerial route directly to the flag and don't consider other options at all. I doubt you'll see everybody hack out of the rough with a wedge without any thought.
