CHICAGO — The Big 12 split North-South. The Southeastern Conference divided East-West. The Atlantic Coast Conference gerrymandered its divisions into a maze few people today outside of Tobacco Road can name with authority.
At a defining moment in the history of the nation’s oldest athletics conference, Big Ten Conference officials and the schools’ athletics directors last summer had options for slicing its 12-team football league into two parts.
Most college athletics conferences divided based on geography, and that legacy nationwide remains ambiguous. It works in the SEC where five different schools almost evenly distributed in the two divisions have won BCS football titles since 1998. It failed in the Big 12, where the southern schools — specifically Texas — commanded more power than its northern counterparts.
“We actually had models of other conferences we didn’t feel had done as good of job, and we were able to see the consequences there were as a result of that,” Michigan Athletics Director David Brandon said.
Big Ten officials studied how other leagues divided themselves and saw how geography often deterred competitive balance. It also spurred discontent among membership. Carving the league in half at the Illinois-Indiana border was the simple solution with six teams in the Eastern time zone, six teams in the Central time zone.
