The Big Ten might be the most intriguing conference in the country this season. The four superpowers in the East Division all enter with different levels of uncertainty, either with new quarterbacks or new offensive coordinators. In the West Division, a case could be made for any of six teams to reach the championship game in Indianapolis. Nebraska is considered the favorite coming off a 4-8 season. Dave Revsine of Big Ten Network joins AP's Ralph Russo to preview the conference. Is this finally the season Michigan and Jim Harbaugh break through and win the East? Has the rest of the West caught up to Wisconsin?
