Things can change quite dramatically within a Test Series. Swanny'!s cowardice when he bottled it is just one example....poor old Trott and Banger's decline's were sudden and unexpected as was Thorpe being reined in by his Mrs. Lots can happen remember Mitchell Johnson!
This series could see the end of Anderson and Broad if the Aussies get after them. They might go at the end if we win The Ashes or in the middle of the series if injured or one does a Swanny.
