Just because something is done in Cyc (or DBpedia, or Freebase, or SUMO, or 
...) some particular way does not mean that it should be done in schema.org 
(or DBpedia, or Freebase, or ...) that way.  This would be true even if the 
goals of Cyc (or ...) were very similar to the goals of schema.org (or ...). 
However, just because something is done in Cyc (or ...) in some particular way 
does not mean that it should *not* be done in schema.org (or ...) that way.  I 
would hope that even if we think that the people behind Cyc are not giants 
that we can do better than otherwise if we stand on their shoulders (or maybe 
on their toes).



The reason to have sub- and super-sports is to be able to talk about sports at 
different levels of granularity, letting content producers describe their 
information in a natural way but also letting content consumers extract the 
information that they need.  There are lots of concepts that can benefit from 
this sort of treatment, from artistic genres to professions to cuisines.



One reason to look at the precise details of how Cyc handles this 
representational meme is to see how a powerful representation formalism can 
provide support for many aspects of the meme.  The Cyc-based solution can then 
be examined to determine better ways to support the meme in less-powerful 
formalisms.
