KM, If you look at the vision, 1 player went defensive side and closish to Serong, but I think thought he was to involved in being traffic cop to get the footy, one was shoulder to shoulder with Bolton defensive side. The third wanted to line up on the circle alongside Brayshaw, St's attacking side. Pretty much where Serong took the footy from Darcy's soft tap. Serong then pushed Brayshaw back almost to the front edge of the square, taking the St with him.
Had Serong been observing that umps bounce error all day and bet on that type of bounce? Bolton was also very quick to leave the inside contest to the outside where Serong needed him.
