All this spouting off about how great the Boks were in these years is a bit of a fallacy.
In 2007, what would have happened in pool A game if Tonga got an extra try...look at the scores...
Pierre Hola, all deft chips and shimmies, sent a cross-kick over to the left, where Suka Hufanga beat Percy Montgomery for a supposedly consolation try on 70 minutes. That was 27-15, but then Hola was at it again. Another cross-kick, this from inside his own 22, sent Tevita Tu'ifua off into Springbok territory. Another little dink into space and suddenly Viliami Vaki, part of a brilliant Tonga back-row, was winning the race for a try under the posts. 27-22.
In 2015 we were not so lucky against Japan...ol Maaikie has never forgotten this.
Both these WC's we lived dangerously...never convincing but 2019 was a huge difference.
