American professional sports fans are laid back and more relaxed. If you attend games, you will easily notice that many don’t follow the game in detail, they only follow parts while eating and chatting to each other about topics that are not related to the game or on their phones texting and surfing the net. They are more inclined to acknowledge greatness of players who play for other teams, unlike sports fans, particularly football, in most of the world where they believe that their players only are the best and other teams’ players are just rubbish or some sort of criminals. For instance, American professional basketball fans of any random franchise would easily acknowledge that Kareem Abdul-Jabbar, Magic Johnson, and Koby Bryant of the Los Angeles Lakers; Michael Jordan of Chicago Bulls; Larry Bird of Boston Celtics; Hakeem Olajuwon of Houston Rockets; Charles Barkley of Philadelphia 76ers and Phoenix Suns, Tim Duncan of San Antonio Spurs; etc. are top notch players that they very much enjoyed watching, even if they have never played for their teams. Same applies to fans of American football, baseball, etc. American college sports fans have more intense rivalry than professional sports fans.
