We seem to be going around in circles dont we ?
1. I think with Harmison(which means Harmison in full flow), England are the second best attack in the world
2. Without Harmison, they are more or less at par with Pakistan - one can argue either way- and India on certain types of wickets.
3. With Harmison, they may be able to surprise Australia, just may, along with their present batting side.
4. Without Harmison, they would not be able to surprise Australia (within the realms of imagination...anything is possible of course). However, without Harmison, they may still be good enough for most other sides in the world.
Note : without Harmison means Harmison in present miserable form.
This is what I think.
