The 26-21 defeat in the opening Test of the three match series has left Jones and co with a mountain to climb in Pretoria this weekend and they seek to keep alive their hopes of repeating the success of the 1997 Lions.
But the Scarlets and Wales outside half, who is still searching for his first Lions test win after four appearances, believes his side can turn things around at Loftus Versfeld.
"It's obviously a huge disappointment to have lost the first Test, but we left ourselves a huge mountain to climb going into the last quarter," admitted Jones.
"But we created a few opportunities and, had we been more clinical, things might have been different - we didn't take the chances until the last quarter. I thought the centres played particularly well, created a lot of problems, and our patterns worked.
"Our fitness levels were also good and these are the areas that we can look to take into the next game. There are others, though, that we need to address as well.
"I thought we grew into the game as it progressed and we managed to get the ball through our hands a bit quicker. We became more efficient in the contact area and we created more problems."
Jones was happy with the character and belief demonstrated by the Lions and knows that if they can put their complete game plan together they can cause the Boks huge problems.
"We have to be honest with ourselves, work hard this week and address areas where we are not so clever at the moment," said Jones.
"I was happy with the way we were playing in the second half, the speed of the ball was good, we were playing with a lot of width in our game and I thought we were causing a lot of problems. But we left ourselves too big a challenge.
"The Boks started very well and got a lot of points on the board early and that made life difficult for us. They silenced the crowd and we didn't get much momentum then.
"We showed good character and belief and when we do implement the game plan, it worked. The big challenge for us is not just to play for sections of the game but the whole 80 minutes.
"We are lucky because if this was a World Cup final, that would be it, the tournament would be over. But we are fortunate that we have another opportunity this Saturday to get level in the series.
"We take a lot of heart from the fact that when we play, we can play some good rugby and cause problems and that is how we have to go into this game."
