We had enough probs at number 3 without needing a new number 4. Assuming Vaughan is unavailable then I might go with Bell at 3 and Hildreth at 4. Form has to count for something.
When I see this thread title I just have this image of Pietersen running, grabbing the urn from its little place and then running away with it.. maybe to stanford? Or back to SA and this was all part of his plan!
