Sixty-four teams. Four conferences of 16 teams each. Two divisions per conference of eight teams each. Eight total division winners play for four conference championships, enter a four-team playoff for the title. Each team plays every team in their division plus two or three. So nine or ten total regular season, plus conference championship, plus playoff, plus national championship means at most 13 games played in a season.
No more Vanderbilt, Northwestern, Iowa State, Wake Forest, Duke, etc etc etc.
This is the way things should have went when the BCS came about.
