Famine: I never said the assumption was incorrect, to assume they are the best in the world is at the very least, reasonable. I have only discussed the definition of the word. By DEFINITION, the winners of the Superbowl are not World Champions.
Yes, I was incorrect about your nationality, I didn't actually look where you were from, I had mistakenly read the bit under Omnis' name, so for that, I apologise.
Other than that, I stand by everything I said.
The best analogy I can think of right now is Drifting back at the start of the Millenium (2001) when the only serious competition was occuring in Japan. At the time, the Champion was Taniguchi. Now just because he is the champion of the biggest national series in the world, and because that series was of the highest standard, it is totally reasonable to assume that Taniguchi was the best in the world. HOWEVER, he has not taken on anyone from outside Japan, and so it has NEVER been said that he was 'World Champion'.
There are other examples of this with various different 'national' sports all over the globe, but the only one that thinks it has the right to call it's winners 'World' champions is the US.
Why, just because a sport/country is bigger, does that suddenly change?
There are professional American football teams all over the world, you've jsut never heard of them because they never get publicity because the sport is not very big outside of the US.
