The bigger Big Ten is ready to go.  After talking about the move for more than a year, the biggest addition – No. 10 Nebraska – will begin its season Saturday and all 12 conference members are in action this week in a league that will have two divisions and a title game for the first time.  Cornhuskers coach Bo Pelini says there’s a sense that finally they can focus on football.  It was a tumultuous offseason in the conference with four new coaches hired, including Ohio State’s Luke Fickell after the 18th-ranked Buckeyes dealt with a scandal that cost Jim Tressel his job.  The season kicks off when No. 11 Wisconsin hosts UNLV on Thursday night.
