In singling out Curry as a Legend, I go with the notion that music plays a huge role in the sport as well as in shows, and he was exemplary. This thead for me is more about listing personal favorites as being legendary. If Jumps are the cornerstone of figure skating, I would agree about Plushenko being a legend.
btw. Look up the difference between the noun Legend and the adjective Legendary. The semantics of it all.
