Every now and then, calls for the jackal to be banished from rugby seem to get a little louder.
They returned recently after a couple of nasty long-term injuries occurred, with more than a few pundits calling for the jackal to be dispensed with altogether. Former Wales captain Sam Warburton's voice was not among them.
Granted, the two-time Lions captain was one of the finest exponents of the jackal in the modern game, so you would hardly expect his answer to be any different. Regardless of that, it is still an issue he feels passionately about and you will find few more fervent defenders of the art of the jackal than the former Wales openside, with the likes of Stuart Barnes and Brian Moore arguing very much the opposite view.
