Che, I didn't make these stats up.... you can find the sports growth stats anywhere on the Net. The last Soccer World Cup was a disappointment in terms of exciting games and bad refereeing ... and if rugby keeps growing the way the numbers are showing then the claims are that globally it will catch soccer up. Plus the Rugby World Cup is played when the NFL is off-season.
that might be the only thing that gets it airtime in the US...
but you still have to compete with the world series and the NBA Finals....
regardless it would really be just a gimmick here in the US
but like BF said id much rather watch rugby than soccer thats for sure
