Virtually no competition.

While professional soccer is still struggling to find a firm foothold in the United States, in the 1970s the North American Soccer League marked the brave first attempt to introduce the game to American sports fans. While most teams had only limited success at best, one did manage to break through to genuine mainstream popularity - the New York Cosmos...

...It was the brainchild of Steve Ross, a passionate soccer fan who was also a major executive at Warner Communications.

Max Ross told his son Steve: "In life there are those who work all day, those who dream all day, and those who spend an hour dreaming before setting to work to fulfil those dreams. Go into the third category because there's virtually no competition".
