Unfortunately, Nellie kim's performances have been overshadowed by Comaneci's but real lovers of gymnastic knows she was fantastic. And the most important, she's really fine with her career and her life:
“Yes, we were rivals. Big rivals. We didn’t talk, but we respected each other, and that was the important thing. I was never jealous of her or mad at her when she would beat me. She was the best all arounder, I wasn’t. Everything she has made, she deserved it. I was better on vault and floor and that’s it. Nadia is five years younger than me. It was a fight between a woman and a girl. And still I won against her, which wasn’t easy.”
