The home team was well beaten with 113 races in the first test in Pretoria, but returned to expectations to win in both Johannesburg and Cape Town over the number one team in the world.
“We have a young, talented group,” Elgar told reporters. “The experience is not there, but we get it and get better every day.
“It was unreal to see how a group that doesn’t have the ‘names’ could come together and play as one. This is a proper unit. It was a proper team victory.”
Elgar admits he did not pull any strings after the loss in Pretoria and says there were some tough talks in the group.
“Ultimately, if you want to operate at a high-performance level, you have to have hard, hard chats. If guys don’t like it, it’s up to them to deal with it,” he said.
“I’m a bit of an old school mentality with a new school twist, but I put some real challenges to some senior players to stand up and react. It was brilliant to see the boys take the message on board.
“If you want to be world number one in the future, you have to compete and beat the best.”

South Africa, who won their previous series in the Caribbean in June, will play test cricket next month when they tour two matches in New Zealand next month.
“We are by no means the finished article,” Elgar said. “But I’m already thinking of the next series, which is something I have to try to control and control, because I want to burn my brain out.
“There are a lot of positive things in that series, but also a lot of negative things we have to hit our heads on.”
