I suppose the corner the game has got itself into is that people now want every decision articulated.
I don't think it has been communicated publicly, but the Kriel incident looks fairly easy to decipher.
a)TMO = Ben Whitehouse, pretty sure he looked at the incident with all the angles he had, on first view live it looked problematic.
b)after reviewing all the angles, he probably concluded:
i - initial contact shoulder to shoulder, through ball
ii - arm wrap present
iii - minimal head contact during tackle.
point iii people will debate, especially when looking at a still frame, but it is clearly cheek to cheek and heads alongside each other.
So conclusion - "no foul play". Does he need to tell AG that there is no foul play?
Does WR need to communicate everytime there is "no foul play"?
obviously not, that would be ridiculous.
for those who still haven't looked at one of the other views available to the TMO, here is the reverse angle again
edit:
doesn't seem to be many concerns over SCO8 Jack Dempsey not going for an HIA, he played the full 80 minutes.
