Mark,
I understand your concern, but look at this gambling notion through the eyes of Tigers round...took a gamble on #13 (admittedly, due to breaking the ideal club on #11) and it paid off. Then he took a bigger gamble on #15 and it bit him. I seriously doubt he would have hit that ball in the water on #15 if he were 1 or 2 back, but being 3 back all the pressure was on him and he didn't pull it off. When birdie is good enough, he hits over the middle of left side of the green or just lays up for a pitch...
I think Zach forced Tiger's hand and so the best way to view the value of those holes now is probably by how they impacted Tiger. IMO.
