Dave once again you have mentioned that the Boks had 20 minutes in the bin, as if that evened up the NZ red. So I have dumbed it down for you:
Minute 2 Frizell gets a yellow…..NZ down a man for 10 minutes
Minute 27.. Sam Cane gets a yellow upgraded to red before the yellow is done…..NZ down a man cumulatively for 53 minutes
Minute 45 Siya Kolisi gets a yellow…..NZ down a man cumulatively for 43 minutes
Minute 73 Kolbe gets a yellow for 7 minutes….NZ down a man cumulatively for 36 minutes.
So no the Boks were always even or a man up, They were never down a man. For 36 minutes of the match they were a man up, which is an advantage. Obviously this varies with circumstances. But there was a comprehensive study in the Premiership. Here are the results:
The 2022/23 Premiership season saw teams during a ten-minute, or sin-bin length, period score an average of 3.44 points with 15 players.
When reduced to 14 players, this dropped to 2.23 points, and only 1.68 when playing with 13.
Conversely, a full team would concede an average of 2.97 points, with this figure growing to 4.91 points with 14 players, and as high as 9.5 points with 13 players.
So teams scored 3.44-2.23 points less and conceded 4.91-2.97 more points, during a yellow card. That adds up to 3.15 points lost during 10 minutes or 12.6 points lost for a full half.
For the net 36 minutes the ABs were a man down that’s 12.6 * 36/40=11.34 points.
Now perhaps scoring is higher in the Premiership than a WC final. But even if it was double the ABs would still have been disadvantaged 5.67 points. This is far greater than our one point win margin and so, for honest supporters, it detracts from our win. Especially as we can see worse head contact not even being carded in the current RC.
I hope that clarifies things for you. As for your rebuttal that we played without a hooker for most of the game that was entirely due to a calculated decision Erasmus made. And for those who think he is a genius, one which undoubtedly, the er great man decided was in the Boks best interest.
I trust you can follow the simple logic.
