Zamora , goal kicks and rugby

Must-read piece by Steve at Cottagers Confidential. Hadn't considered the goal kick angle, and part of it might be Roger Johnson, but still. (also, what happens to second balls off these goal kicks?) Question: why don't we build from the back with every goal kick?  Field position, no doubt, but you don't find players lamping the ball to the corner flag like in rugby, which would make more sense as a ploy.
