Brazil's humiliation in Wednesday's World Cup semifinal sent shock waves through the All Blacks Sevens team.
Sir Gordon Tietjens said it was a timely lesson for his team, in camp this week at Mount Maunganui before they fly out to Glasgow on Monday.
"I pulled the boys into a circle and asked them what were our learnings from the Brazil-Germany game," Tietjens said.
"Brazil went in as hot favourites with an impeccable record, and they got a hiding.
"I don't know how they prepared but that is why it is so important to do everything right in terms of your preparation, your mental and physical build-up, and you just can't take any short cuts.
