Hookers are usually a gnarly benchmark for Super Rugby sides.
Some of the younger brigade have not collected the creased faces or disfigured ears which often signify combat in the scrummaging trenches and close-quarter combat.
They may fancy they can dance a wider track too in ball-carrying raids on lighter backs. However, coaches everywhere are looking for men who can perform their core duties first.
It may be unglamorous work but without accurate lineout throwing, hearty scrums and metre-seeking drives, Super 15 teams suffer.
The Chiefs' Mahonri Schwalger and Stephen Moore at the Brumbies are hookers who have seen it all in their careers and are still finding new levels of performance.
