I think he's talking about Artamonova going to London.
AFAIK she went to London with a injury and didn't play a single match. She also went to Beijing after being already retired...wasn't playing well in years at least in terms of NT
When I mentioned Artamonova case, I wanted to point out she went to the Olympics more than one when she wasnt part of the whole process, the whole Olympic cycle. She came back more than one time in order to get the so desired gold medal. She wasnt great like during the 90s and early 00s, but she was called cuz she was quite solid in reception.
She did almost all the dirty job in the IOQT in Japan in 2012, where Russia finished undefeated and she was starter.
She went injured to Athens 2004. I really dont remember her playing any match. I remember her always in the bench. Actually, praying in the epic SF match against Brazil.
In London 2012, she played some matches as starter. Like it was pointed out, she did a great job with Kryuchkova in reception. But on the main matches, she was benched by Sokolova.
