Don't agree with you there Melts, we are missing Harmison, Jones and Giles who are 3 front line bowlers. Whilst Giles is certainly not world class, he is an experienced and wily test match performer, he is also a more than useful lower order batsman.
The whole balance of the side has looked wrong in this series, the batting is littered with too many stroke makers in the top five, four of which I would class as flair players, we have desperately missed Vaughan's ability to come in and anchor the innings, and IMO Collingwood is batting too low down the order to play that type of role.
