That the Aussies couldn't get the basics right was one of the main reasons they took such a tonking. Normally these basics would (and did) include such aspects as leaving the ball alone, taking catches, not getting run out, tying the opponents down. That one had to add 'Not bowling no-balls and in the process costing yourself wickets (plural)' would not have been expected to form part of that list. Especially as one was from a slow left-armer.
Good on yer, boys.
