I'm liable to agree with the convention that low blows shouldn't be allowed, although I think anyone bringing in high-waisted shorts to take advantage of this should get a kick down there to try and teach them a lesson.

With the protector in play, I think the effect on mobility from the hip or leg shots can be just as bad as the shots to the nuts. And after all, it is what has helped to make boxing the sport of kings it is today, fought by entirely honourable and gentlemanly pugilists.
