The vision of a year-round sports and entertainment hub in New York's Nassau County that generates jobs and tax revenue seems simple enough, at least on paper. But compared to major cities with major-league teams, Nassau is a suburban venue. "If an arena becomes an entertainment destination, you don't necessarily need a professional sports franchise," said Joel Maxcy, a Temple sport economist. "As long as you pair it with other venues and entertainment options, it can still be successful."
