Since Lee has not been in best of form except for the newzealand series(admitting they are an ordinary side) ,it would be better for him to take this forced break and come back and find out ways of taking the wickets with new ball.
It is really strange that Australia finding difficult to win in their home pitches, it clealy as indication how well mcgrath,gillepsie contributed for their wins especially during waugh and pointing era but now if teams like southaftrica and india challenge them as they are doing now it would be not be far to call Australia as any other team in the world.
