No Big Ten position group returns more talent and production than linebacker. The list of returnees includes four first- or second-team All-Big Ten selections from 2012 -- Wisconsin's Chris Borland, Ohio State's Ryan Shazier, Michigan State's Max Bullough and Michigan's Jake Ryan -- along with two other former All-Big Ten selections (Michigan State's Denicos Allen and Illinois' Jonathan Brown), plus a host of other potential stars. Eight of 12 teams return multiple starters at linebacker -- Iowa's senior trio of James Morris, Anthony Hitchens and Christian Kirksey has combined for 65 career starts and 662 tackles -- and only one squad (Nebraska) must replace its entire starting group from last season.
