MICHIGAN STATE
Coach: Mark Dantonio (eighth year)
2013: 13-1 (8-0 Big Ten)
Top returnees: RB Jeremy Langford (19 touchdowns last year), DE Shilique Calhoun (14 tackles for a loss)
Early test: Sept. 6 at Oregon
Outlook: The Spartans must replace seven starters from their vaunted defense, including Darqueze Dennard, Max Bullough and Denicos Allen. But several big-play guys return, including Calhoun and defensive backs Trae Waynes and Kurtis Drummond. Quarterback Connor Cook was a second-team All-Big Ten selection, their offensive line is solid, their receiving corps is deep and Langford reeled off eight consecutive 100-yard rushing games as a junior.
