South Africa came from 21 points down to defeat England 42-39 in a thrilling first Test at Ellis Park on Saturday.
George admits the squad were left exasperated after squandering their lead, but says they are keen to redeem themselves.
"Last week wasn't the start we wanted and this wasn't the home start we wanted. We were almost very, very good, so hopefully we can string a few things together and get that 80-minute performance next week", George told reporters. Looking back, we probably got out of jail free today, but just as they could have put us away, we could have put them away.
George added that the players needed to take responsibility for the errors that allowed South Africa to score five tries in Johannesburg.
"It was a tactical mistake on my part, but as soon as we realised we needed more width on defence, and the players adapted on the field, things started going our way", said Erasmus, who admitted that the Boks will have to make a number of "brave decisions" in the next couple of months.
"We knew that wasn't what we worked on during the week".
Three uncompromising places for visitors to play, three touring teams bruised and with much to contemplate ahead of the second round of Test matches Saturday.
"Owen Farrell has settled in well to his new role, with the senior players supporting him, and there is a good feeling within the camp".
