Tiger's drive on 17 hit a tree high up, careening it down into the second cut, after which it took a big hop forwards until it hit another branch that threw it right down on the path.
The next shot -- incredible attempt -- put him in the bunker, which was bogeysville given the position of the hole and the slope of the green away from that bunker.
Now, no trees, what happens? His drive keeps going left of left, and now he's got no shot because the location of the hole, the bunker, and the fall-away slope of the green have put him way out of position -- the opposite side of where he needs to be.
Does he make bogey from there? Maybe, maybe not. But more importantly he might lose a stroke to the field because he played the hole wrong relative to the hole location. The correct line to that hole (on a treeless hole) is right center or right.
