Whites becoming the minority in sports?

As I read the articles in the first lesson a repeating statement I have seen is that African Americans are starting to make a more prominent role in sports. Early in the sporting years in the United States teams were all white. They had African American leagues separate but the white leagues were the big time leagues. As the years progressed African American players started making an appearance in the leagues. This continued to rise in numbers as the years went on. Recently in the past few decades African Americans have surpassed the numbers of white players. In sports like basketball and football, teams are consisting of more African Americans than whites. It seems that now white players are becoming the minority in certain sports such as football, basketball and track and field. Some people talk about certain positions as being only white positions like quarterbacks but recently if you look at the number of African American quarterbacks are increasing in numbers and they are all very very good. Are white athletes in certain sports becoming extinct? chances are no but for now it looks like we still have hockey!
