Heyneke Meyer calls them "soft moments", lapses of discipline which can change games and turn coaches against their walkie-talkies.
Having attempted to throttle his two-way radio during the Springboks' loss against Australian in Perth during one particularly daft act from one of his players - a shoulder charge by prop Tendai Mtawarira - he hopes his side will keep them to a minimum against the All Blacks in Dunedin on Saturday.
And that explains his conservative selections today. Meyer has made only two changes and one of them was forced - lock Flip van der Merwe in for the suspended Eben Etzebeth and Francois Louw replacing Marcell Coetzee as openside flanker.
Morne Steyn retains his place at first-five despite his largely negative approach to the game and the challenge of 20-year-old Johan Goosen, with Zane Kirchner again named at fullback ahead of 21-year-old Pat Lambie.
Steyn had an ordinary Super Rugby season with the Bulls and there is a feeling that he and the Springboks are struggling to keep pace with the modern game. Kicking the ball away doesn't reap the benefits of two or three years ago and the All Blacks have counter-attacking threats in their back three which could send Meyer's blood pressure even higher than it was in Perth last Saturday.
