The Big 12 is talking about expanding again in an effort to regenerate itself back to 12 teams.
Since most major universities have found a home in one conference or another, their options are primarily schools considered respectable mid-majors in football such as Cincinnati, BYU, Houston, Memphis, UConn, etc.
However, as always when this comes up, some people are talking about Arkansas leaving the SEC for the Big 12.
The points are always the same. Fayetteville is much closer to a geographic fit with the Big 12 than the SEC. Arkansas has historical ties to all the Southwest Conference schools.
