I said above that the feat should not be called impossible, just as you have said here. But I was not implying that there was a reasonable chance that the feat occurred. As I said farther above, I still cannot see how this would be possible. We know, at minimum, that even the best returners are routinely forced into errors on the return. Saying so takes away nothing from the quality of the returners, because it has nothing to do with them: these are forced errors. It happens to the best returners and it happens often. So two weeks without making a return error -- it is so farfetched that I cannot see how it would occur.
