When i was a young boy(like 7 or 8 years old), in my imagination i created an imaginary soccer league in USA, that was the best in the world.The best players in the world were playing there, and the level was so much higher than that of the rest of the world, that no player from the rest of the leagues could play there, no matter how good he was in the country he was playing, even if that country was Italy or Spain.It was something like NBA, but in soccer!!One of the biggest problem for the rest of the players to play there, was the fact that the courts were bigger,and just like in nba, the dimension of the courts were bigger.What happens in NBA? you shoot for the 3 point shot, almost 1 meter farther than the rest of the countries!Also the total length of the court is bigger.In my opinion, this is one of the most crucial factors that leaded to the superiority of NBA , compared to other leagues.The players were trying to adjust in more difficult courts, and so they became stronger, faster, and improved their technical skills better than their colleaques.The players of NBA became so much better than their collaques from all over the world, that gave NBA a great prestige.
Lets see now what happens in soccer.Currently soccer in USA is becoming more and more popular, and the level is raising.But still, its so far away from to be considered the best in the world.What can be done so the level of the league to be raised?One option is to spend a lot of money and tranfer famous players from all over the world to play in USA.Of course this will raise the level but you need a good level of native players too.According to my opinion, a good way is to raise a little bit the dimensions of the court(longer, wider, penalty spot farther, etc, just like basketball).When players of this league go to play in other courts(smaller) in other countries, it will be like playing in the playground.Of course the other teams will be more adjusted to these courts , but the superior players will be those that usually play in bigger courts.
One can say that by enlarging the courts, what we see will be more boring!But i wonder how boring are the games in barcelonas stadium or maracana, that are considered among the biggest stadiums in the world.Besides, players will adjust to such courts, and diminish their difficulties.Also , i think that the quality of the leaque is made of the quality of the players, and having the best players, makes the best league that everybody wants to watch.
Of course this can be a fact for every country.But i used USA because 1)of my childhood imagination, and2)because soccer in USA is a new stuff and its under construction, and its easier to make these changes.This can also be considered for some asian countries that want to build strong leagues and improve their level.
