I've actually met guys in the southeast part of this country who truly believe the best African American football players come from the south because they have "slave genes". I'm not making this up.
That is essentially what Jimmy the Greek said after, IIRC, he'd had a few drinks at a dinner, and unfortunately for him it was caught on film. He was promptly fired from his job on "the NFL on CBS" and was never heard from again.
Edit: sorry I missed seeing Hetuck's post, didn't mean to be redundant.
