I commented on that in another post, and as much of the blame should be placed with the players up forward who do not go hard and fast at the ball, as is placed with the Suban's etc who are kicking forward under pressure. If Suban can see a fella like Walters running hard to a vacant space, he only needs to put it out into that space. If Walters is standing still, ( which is very rare for him) Suban has to be pinpoint accurate, and that doesn't happen often under pressure.
When Ballas was under pressure on his left on the boundary early in the game, the reason he saw Walters and kicked to him was that Walters was moving hard into a space.
