It’s funny how you can rely on the guys who’ve played 300-and-odd one-day internationals in these major tournaments. And by ‘funny’ we of course mean ‘predictable’.
Mahela Jayawardene has played so many one-dayers that his average (33.40) is meaningless. What you actually need to do is split his career into several manageable sized careers in order to be able to compare him to others. His efforts span so many rule changes and so many different Jayawardenes, it’s pointless to try and comprehend his efforts as one whole.
Australia, by way of contrast, are best evaluated cumulatively, as if all eleven components comprised just one all-rounder. Looked upon that way, they’re a decent player – not earth-shattering, but pretty consistent.
