Erasmus admitted the performance was far from perfect, but its red-hot core of sustained power and aggression delighted the coaching team.
“We felt in the previous five or six Tests this year it hadn’t been really consistent but I think in this Test match our physicality – which is one of our strengths – was there consistently throughout the game and I am really proud about that,” said Erasmus.
“Tactically and technically there were definitely some mistakes and errors but I think the way the guys pitched physically was what we wanted to get out of this game.
“I think if we want to go all the way that’s something that we need in our game.”
Cheslin Kolbe (2), Makazole Mapimpi, Bongi Mbonambi, Lukhanyo Am, RG Snyman and Malcolm Marx all scored tries while Handré Pollard kicked six out of nine attempts at goal to take his Test tally through the 400-point mark.
It means the Boks have scored 17 tries in their three Rugby World Cup matches to date – something which had pleased Erasmus, although he conceded that there was room for improvement.
“We definitely have to get better on the attacking side,” he said.
“We saw New Zealand scored nine tries two nights ago and we scored nine tries four nights ago. They scored them in different ways and we scored them in different ways.
“Some people enjoy the way New Zealand score tries and we enjoy the way we score tries.
“I’m not sure how many tries we scored tonight but we enjoyed the way we scored them. We have a certain style of play and a certain type of player; we have played to our strengths.
“We know that the way we performed tonight is probably good enough to get us through to the quarterfinals.
“We know we have to have some improvements on attack, definitely, to progress to semi-finals and finals but that’s not the only area we have to improve.
“I thought we were better at scrum time against a good Italian pack until we went uncontested. I thought we were good at mauling; we were good at the breakdown in the physical areas but surprisingly we were bad at discipline on defence.
“I wouldn’t single out attack as one of the big worries because we’re currently scoring tries and are right up there with New Zealand and the other teams scoring tries in the difficult conditions and humid weather. We’re pretty happy with the amount of points we’re putting on the scoreboard.”
Springbok captain Siya Kolisi was also happy with the progress that had been made.
“We definitely stepped up a lot today from the first minute,” Kolisi said.
“From the scrums as well. When you see a guy like Beast (Tendai Mtawarira) so keen to scrum every penalty and how crazy he goes it really inspires you – and that’s all the coach asked us for – intensity and work rate and we did well in that.”
Meanwhile the first indications were positive in terms of injuries. Kolbe left the field in the final two minutes with an ankle injury, but it was not thought serious.
“His ankle’s fine; he rolled it a little bit,” said Erasmus. “He played a wonderful game both on attack and defence – aerially – he was just fantastic.
“I think at this stage he must be one of the players in the world with Sevu Reece and Damian McKenzie, those kind of players who have just got x-factor and can do something out of nothing. It’s wonderful to have him in our team.”
The Springboks complete their Pool B programme against Canada in Kobe on Tuesday (kick-off 12h15 SA time).
