Zealously supporting Jason Day today - when he arrived at the tee, I was reminded of Matt's mention of TOC above, my greatest fear for him on 18 is that he would make double and JS make birdie. It is not the fear that JD would choose the wrong strategy up the 18th, but that everything is so penal, that this is potential to make double everywhere, I mean everywhere.
TOC, on the other hand, for gifted players like this, they can choose their strategy to play the hole to achieve their desired outcome - safety, or go for everything. Adam Scott showed how to make a double by hitting it OOB on the road, but that is highly unusual, but possible, but it is also 100% possible to take that shot out of the equation, unlike 18 at WS - where danger is everywhere.
