Breeding

This guy studied breeding the same place as Jimmy The Greek. For those who don't rememeber, Jimmy The Greek was a professional odds person in sports. He was also a commentator for CBS Sports if I remember correctly. He was doing an interview and was talking about how and why the african american was a good runner. He said it was due to their large and muscular thighs. They were bred that way or something to the effect. He was promptly unemployed.
