It's quite comical the way players - seeing as they can't help copying each other - very carefully try to place the ball on the very edge of the corner arc, as if they're masters of some dark art, and then proceed to punt the ball straight at the first man, as usual. It's as if their brains have been so drained by the prospect of being naughty with the placing of the ball almost outside the arc - ooooh, and I'm doing it right under the linesman's nose, ooooh, I'm so daring! - that they can't concentrate for the kick itself. They need to bloody practice!
