Racism of African-Americans, also Asians?

Throughout the NBA you may think to yourself, "how can there be racism in the NBA with all of the African-American players in todays sports leagues?" However, if you look at some of the key numbers you realize that although there are very many African-American athletes, there are very few African-Americans who hold prestigious positions. 9 of the best 12 teams in the NBA are led by White coaches so owners rather hire a white coach than a black one. There are 5 African-American general managers in the league and only 1 black owner, oppose to 28 white owners! And, that black owner happens to be the infamous Michael Jordan. Now, who would have ever thought that there would be stereotypes of Asian athletes? It is believed that Asians are supposed to be good at golf, baseball, tennis, and figure skating, but not at basketball or football. Due to this stereotype, they are often overlooked by college recruiters and professional scouts simply because of their names!
Lets talk about Jeremy Lin. Jeremy Lin was selected as California's high-school player of the year, a prestigious award that only is awarded to one person in the entire state! Jeremy Lin also led Palo Alto High School to a state championship. In regards to college, neither UCLA nor Stanford offered him a scholarship. I recently watched a clip of "60 Minutes," on Jeremy Lin, and he had said "the obvious thing in my mind is that I was Asian-American which, you know, is a whole different issue. I think that was a barrier. I mean, it's just a stereotype." Because Jeremy Lin is one of the few of his kind people tend to think its amazing the things he has achieved, however, if he were to be African-American many people would not think it would be so amazing. This is how society works, and it really is a shame.
