With Friday's victory, her resume now includes three consecutive Olympic Games, a gold medal in the 2011 Pan American games and a 10th place finish in the 2010 World Championships.
In the past two Olympics, Johnson narrowly missed making the finals, essentially finishing 10th in both Athens and Beijing. London will be her final opportunity for the Olympic medal she covets.
“She has a shot,” Caven said. “I am telling her she can win gold. If she hits everything right, there is no reason why not. I have seen this before. When guys know it is their last chance, they pull something out they have never done before. If you are in it, you got a chance.”
Johnson said an Olympic medal would be the pinnacle of her career, but even if one is never draped around her neck, she will leave the sport with no regrets.
“It's a big honor just to be there and be considered one of the top athletes in the world,” she said. “There will be some disappointment if I don't medal in London, but you have to walk away and be OK with that.
“I have gotten to travel all over the world. I have friends now from all over the world, which is pretty incredible, I think.”
