While the Boks only reported one injury – prop Jannie du Plessis has a broken tooth – it was the mental scars they have to overcome.
“We want to make ourselves and our country proud,” said Van Graan.
“But like our captain and coach said afterwards, no excuses, we have to fix this, and we’d like to do it this weekend against England and win on our own terms.
“After the game there was a lot of emotion from my side, obviously very disappointed in losing that game, but we had a good look at the game. There were a lot of positives but also some negatives,” he said.
Looking at the stats from the Test in Dublin, Van Graan said the Boks should have done more with the mountains of ball.
“Territory we dominated, 63% and 55% possession, I felt even though they kicked behind us, we won the territorial battle, executed our kickoffs, executed our lineout plan, scrums were brilliant and very happy with the maul try.
“But too many handling errors, not clinical enough, and definitely something we’re going to work on for this weekend. It was a proper Test match, both teams made mistakes, a lot of pressure and another valuable lesson in the game of rugby.
“It’s not the amount of possession or territory that counts but what you do with that, so we need to be more clinical and obviously there’s one or two things to fix,” Van Graan said.
