In theory, that should end the need for the TMO to trawl through endless replays trying to determine whether a try has been scored or not. Instead, the referee will say they think it was a try and the TMO will look only for an obvious reason to disagree. The intention is to speed up the game and cut back the length of time it takes for Super Rugby matches to play out.
While the playing time is only 80 minutes, frequently games last year were taking two hours. The constant TMO reviews were the main driver of the added time with some incidents taking more than four minutes to sort out.
There were also several occasions where the TMO overruled the referee and others where the referee overruled the TMO.
The second change is the addition of what is effectively a full-time judicial committee to monitor and rule on foul play. A permanent three-man panel consisting of New Zealander Nigel Hampton QC, John Langford of Australia and Stefan Terblanche of South Africa will meet at the end of each round and review all incidents involving red cards and citing commissioner referrals.
They will then inform players within 24 hours if there is a case to be answered or need for a sanction to be imposed.
By having a permanent panel, Sanzaar hope they will have consistent outcomes and decisions will be made quickly to allow players and coaches certainty around future availability.
As always, the proof of the pudding will be in the eating, but certainly the system makes good sense and a major improvement on the existing way of doing things.
