Baseball has the Yankees and the Dodgers. The NFL, the Packers and the Cowboys. In the NBA, the Lakers and the Celtics are the blue bloods.
College football has about four times as many FBS teams as each of the professional leagues, so it's fitting that the sport has four times as many college football teams that are to the manor born.
That's what blue blood means. In olden days, royalty was thought to literally bleed blue. Science since has proved that only Michigan fans bleed blue, at least among these eight teams.
And there are only eight blue bloods in college football: Alabama, Michigan, Nebraska, Notre Dame, Ohio State, Oklahoma, Texas and USC.
