OKLAHOMA CITY (AP) ― With back-to-back gold medals in the 100 meters, Usain Bolt has already proved himself to be the greatest sprinter at this moment. To former U.S. track star Marion Jones, it also puts him well on his way to earning the moniker of the best track and field athlete the world has ever seen.

“I certainly think based on the fact that he’s still so young and that he’s already accomplished so much that, barring serious injury or anything else, I think that he certainly would be considered the greatest track and field athlete ever,” Jones told the Associated Press in a phone interview Wednesday.

“And that’s based on the fact that he’s so young. This is not a person who’s 34 or 35 years old. He’s young, he’s vibrant, he sees that there’s so much left for him to do in the sport.”
