I watch a lot of world football (Soccer in your language) but I also watch American football and alot of other sports kind of preparing for WC in your country. The only game I have ever seen that competes with the intensity of El Clasico or big games across the world in American sports. No other league seems to have the energy of a rivalry. Why is a College game more intense and full of a real rivalry energy then the actual professional leagues and is it the greatest rivalry in ALL American sports ?
