The reasoning behind the name change was to correct the misconception that I-AA football teams aren't Division I. The nomenclature was designed to help corrent this misconception. The names "Football Championship Subdivision" and "Football Bowl Subdivision" are meant to point out that the former I-A and I-AA are both Subdivisions of Division I and are are only used for Football. One of which plays its postseason in a Bowl system, and the other which plays its postseason as a Championship Playoff. That is the true reasoning behind the name change. All the teams in the FCS are Division I teams and only play in a lower division for football.
