The beauty of soccer is that it's not all clear cut. It's a "soul" sport.
The beauty and soul of soccer lies within the players and their skills, not the temperamental referee watch. The beauty and soul can remain perfectly within a more fair and balanced structure.
This abstract "Europeans won't accept it" and "soul" argument has no substance. I'm more than welcome to hear a real argument against the suggestion.
This happens with every sport I have followed. Cricket, football, hockey, baseball, basketball, tennis and, yes, soccer. There are always the "purists," as they invariably call themselves, who resist change for no other reason than "My sport is different. This is the way it's been, this is the way it must stay." How many Brits were dead against instant replay until their disallowed goal against Germany last world cup?
Player safety, instant replay, and clock management (in soccer), are huge changes every sport is dealing with, and sentimentality ain't gonna cut it.
