I would not cast aspersions on our primary school kids because they would have more brains to implement the strategy successfully.
Y'see, the problem is that they were so inept that they got caught and, in the process, made all Ozzies look stupid (like we have a go at our wonderful Tassie cousins).
I mean, these guys represent us at CRICKET!! It is our religion, no less!! And we look on them as the best of the best!! But they let us down in the brains dept!
I am absolutely certain that countries have done far worse things with the ball than our boys.
