You are correct. Jimmy the Greek said that blacks were better athletes dueto breeding. He said, that slave owners took their biggest, strongest male slaves & bread them with the biggest and stronges female slaves resulting in bigger and stronger offspring.
Maybe Dusty's school-teacher mother can look up this piece of history and clear Jimmy the Greek's name. At any rate, I doubt if Dusty will be run out of town the way a white guy would be if he were to make similar comments regarding blacks.
