ROSEMONT, Ill. (AP) – Commissioner Jim Delany insists expansion remains on the Big Ten’s back burner.  While the national landscape continues to change, Delany says his conference is “as happy as could be” with 12 members. He says the Big Ten is “not in an active mode,” and the conference is simply “monitoring” what’s happening.  Nebraska jumped from the Big 12 and started Big Ten play this year, allowing for two six-team divisions and a championship game in football.  Notre Dame is often linked to the Big Ten. Delany says he spoke to athletic director Jack Swarbrick a few months ago about hockey – not expansion.
