Football is cool.
Going on the sheer weight of opinion (its the most popular game in the world, next closest contender is probably cricket due to the Asian interest) it has value but is it overrated? Dunno, here in England no matter who you are and what team you support / follow you can be sure of finding common ground with almost any other average bloke in the street.
Over rated??? Matter of perception, brings hundreds of thousands of people together with a common interest that crosses boundaries of religion race and nationality once every four years. Millions of people with a common interest, a game so simple that it can be played by anyone of any age almost anywhere, yet a game so complex that team cohesion and tactics can make the difference between a good team and a great team.
Its growing in its appeal as well, the emerging African nations and nations from the Asian sub continent are fielding sides that regularly trash respected European and South American teams. And look whos been doing well in the world cup, the good ol US of A.
Over rated? Matter of opinion
Just dunno
