good comments cypher50 - you get it. thank you.
I think 'ball over the line' or not will be fixed with technology before the next World Cup.
I don;'t see any changes coming to offside or how the decisions are evaluated after the fact - it would change the flow of the game and give too much advantage to attackers to give them a set piece play if they were deemed onside via replay. (Although if you want more goals this would be a definite side-effect)
Football (and it is football, not soccer - you got a man on the moon and we got the Football Association) is gradually creeping into mainstream America. There is interest around the World Cup and the national team. The Americans I know are very proud of having a successful team taking its rightful place on the world stage. Is there another American team sport that has global interest? (sidepoint - A lot of Americans I know regularly confuse the words 'world' and 'America' - its accidental and no harm is meant, but they do it)
I manged to convince two 'merican buddies to come with me at 7am this morning to watch Brazil v Holland in the local Brazil bar....! So where to go from here? The low scoring, low stats, low commercial interruptions format may take a while (decades) to get a hold - the big European leagues have been running for 100 years or so. Add into the mix the changing demographics of the USA, more readily available content on demand (the Internet and TV will be inseparable for all practical purposes within 5 years)and the globalization of the teams - Manchester United are wildly successful in Asia for example - and the path is set. Just don't hold your breath for mass adoption anytime soon.
