At some time, a few big-time Division I college coaches decided to not give great white, high school running backs a chance, but to instead bulk up and play them at fullback or tight end. Then the same happened with cornerbacks, to have them bulk up and play strong safety if they were lucky, or linebacker. It’s now virtually against the law for a big-time college program to have a white running back or cornerback. That of course then translates into the NFL. I am not a racist at all, but I am tiring of the discrimination against great white athletes. When will it go too far, too far for many to tolerate this form of racism?
There is no question that Blacks seem to dominate most sports which require speed and power. In football there are some positions which require strength rather than power. That is why you see a lot of White offensive linemen.
I do think they have gotten overboard with giving preference to Black players. I can recall when the Southeastern Conference was all White, they did perfectly well against the integrated teams of the rest of the country.
