In 2014, the first NCAA College Football Championship Tournament resulted in The Ohio State Buckeyes earning, what many call, the first undisputed national college NCAA Division 1 football champion. Since then, Alabama and Clemson have added their names to the list. But prior that, even the vaunted BCS saw different polls and systems declared national champions based on algorithms, guess, coaches voting and in some cases, perhaps pixie dust.
