You can't compare a setter to an OPP. Setters get better with age because they don't depend on physical factors that much but on experience, whereas opposites get worse when their body gets worn out. Technically Neslihan is just as good as she was 10 years ago, but she simply isn't as fast and as powerful as she was back then, so she's not great anymore. Leo's performance yesterday was world-class. However I agree, to be one of the best in the world she'll have to play on this level for more than one match
Oh I don't agree on that. The only position that doesn't get old is liberos in my opinion. Setters get slower as well, that's probably the reason someone was calling her Leo, the panda when she was playing in GsD. However an experienced setter sure is very valuable too. So it's an exchange between experience and speed.
