Just giving you the take from other officials and stats done of similar offences. I would disagree too that he single handedly prevented the try being scored as maul still went forward and it was 2 other Munster players who held ball up.
Regardless it was not the definitive part of game.
But was telling on line that 4th official wasn't backing up the decision confidently
Correction - the view of ONE other official - which is both a logical fallacy (appeal to authority) and a losing logical fallacy (the referee is a higher authority)
There was one other Munster player on top of the ball carrier - but he arrives AFTER Beirne has turned the ball carrierover onto his back.
If there was a second, then please enlighten me as to which "other" Munster player was wearing a blue scrum cap, and had "6" on his back in big red lettering (numbering?)
It was absolutely a definitive part of the game.
Going back to the TMO lacking confidence is going back to the logical fallacy.
Commentators say as Dunn goes for the line "that's either try or penalty try"
Watch the video, and tell me that Beirne isn't one of the 2 Munstermen, and wasn't the 1 Munsterman who turned the ball carrier onto his back.
Sod it, I'll even break it down for you (patient cancelled)
1: White6 binds on Black 12
2: W6 swims up to reach beyond B12
3: Ref awards the penalty
4: White 4 joins W6, and angles in to split the maul
5: Ball Carrier tries to get to ground, with W6 firmly attached
6: W6 has turned BC, and is on the ground with him, W4 is still on his feet
7: W4 flops on top of BC and W6
8: Reverse angle of W6 & W4 on top of the BC
The only way Beirne is innocent here is if he isn't wearing a a blue scrum cap and a white shirt with 6 on the back.
If you want to see it in motion - watch the video. W6 initially binds onto B1, then B12, then BC.
