The test in Dunedin really was an epic. A full 100-minute production that for all that it thrilled and surprised, it also frustrated on account of the TMO being cast in the lead role.
The issue, in the wake of what was a spectacular game of rugby, is not whether TMO Rowan Kitt made good or bad decisions, it is whether he needed to be making them at all.
Added to that is the question of whether, when he was asked to step in, he was given the right brief and an appropriate scale of jurisdiction.
The dramatic and enthralling nature of the contest can't be used to obscure the staggering statistic that this 80-minute test took 100 to play out, which means that a fifth of the period the players were on the field, they were standing around waiting for a decision to be made.
It's just about tolerable when the rugby is that good, but if it's a dour grind against the Pumas, or a slug-fest against the Boks that drags on for that long, the New Zealand Rugby Union might find that down the track the 1,500 empty seats at Forsyth Barr Stadium starts looking like a great result rather than a source of concern.
If there is an easy and quick solution, then All Blacks coach Steve Hansen says it would be for referees to be empowered to back their initial decisions and not second guess themselves.
