With all the talk of how the Sri Lankan bowling attack is lacking penetration, the Australian bowling attack has only managed 20 wickets once this whole summer, and that was when they got smashed by 300 runs by South Africa
Opponents (unless they are technically suspect) will bat 90 overs each innings against the Australian bowling attack nowadays
As good a spinner as Nathan Lyon is, if there is someone better than him that comes along, they should replace him
EDIT - Got him, but hes saved his team from complete and utter humiliation
