The reason that I posted the definition of the word "collective" is because you have confused it with the word "collectivism." Teams rely on the collective efforts of their players. Fans cheer their teams collectively. Nothing to do with socialism. Zip.

Furthermore, the writer uses the word "private" to signify "not-collective." Any association with private "property" is in your own brain which, unfortunately, has completely mis-read this article.

And again, for the record:

col-lec-tiv-ism, n. The socialistic doctrine that the land and means of production and distribution should belong to the people collectively. [Emphasis added]

Note the correct use of "collective" as an adverb.
