Hi Leonid

RE: “But suppose goalkeeper failed to produce and relies on others to win the game. What will be the outcome? Others simply would have to work much harder. If they win the game a goalkeeper will share the results as a parasite.”

If the goalkeeper “relied on others to win the game” (e.g. just sat down and watched) I suspect the coach would take him off immediately and replace him. And he would hardly “share in the results”, as a parasite or otherwise. He would be more likely to be treated as a pariah.

You seem determined to think of a game of football as if it were a philosophy seminar – with people “exchanging values” (though, even there, it’s an exchange of ideas rather than values). My sporting days are over (alas!) but I can’t recall ever “exchanging values” with other players on the field while the game was in progress. Occasionally, I may have exchanged the odd value with an opposing player!
