How long do you feel it needs to make the review?
On the basis that the on field review should generate all camera angles but doesn't allow the time to fully analyse as the game must go on.
And with the synchronised cameras and split screens the Bunker review should scan through all of those and decide.
If the clock starts when the player is actually carded and the Bunker signal indicated they FPRO is already ahead of the game. They are not starting from cold trying to find an incident and then calling up the relevant cameras.
If they are spending more than a couple of reviews of super slo mo trying to find mitigation it likely doesn't exist and on the flip side if you are taking more than a couple of mins to find foul play that also probably doesn't exist
To my mind clearly allowing 8 mins is more than adequate, if not C+O within that time move on.
But as before I am more concerned about the influence that is now focussed on the Bunker, for both of yesterday's incidents to be considered Yellow only was somewhat surprising, both high impact to head and yet not considered high degree of danger, I do not know what mitigation you can apply for recklessly hitting someone on the ground
and whilst PSDT was the second tackler the dynamics and position did not change rapidly or significantly.
In summary not the fact that numerous events could stack up but the apparent intent to ensure players stay on the field irrespective of the evidence.
