2. Iowa: Kirk Ferentz has built one of the nation's top programs. A big key has been continuity, with defensive coordinator Norm Park and offensive coordinator Kevin O'Keefe being loyal soldiers.
3. Ohio State: Jim Tressel has built a great defensive staff led by coordinator Jim Heacock. The offensive staff will be under the microscope this season.
4. Michigan: It's just a matter of time before Rich Rodriguez gets his system in place and starts winning big. Greg Robinson is one of the country's top defensive coordinators.
5. Michigan State: No-nonsense Mark Dantonio has restored discipline and toughness. Defensive coordinator Pat Narduzzi is a rising star.
6. Wisconsin: This could be a make-or-break season for Bret Bielema. Coordinator Paul Chryst is a top offensive mind, while Dave Doeren is an intense and smart defensive coordinator.
7. Illinois: Ron Zook answered a lot of critics with a Rose Bowl bid after the 2007 season. New offensive coordinator Mike Schultz may provide a needed boost.
8. Northwestern: Coach Pat Fitzgerald continues to grow in the job and is a future star. The arrival of coordinator Mike Hankwitz has given the Wildcats a strong defense.
9. Purdue: Danny Hope takes over after a year as coach-in-waiting. He's a master motivator and underrated technician. Offensive coordinator Gary Nord is a solid veteran.
10. Minnesota: Tim Brewster continues to make strides, scoring a bowl bid last year. Now, it's time to score some big wins. Hiring co-defensive coordinator Kevin Cosgrove will pay dividends. New offensive coordinator Jedd Fisch is an unknown.
11. Indiana: Trouble could loom for coach Bill Lynch, whose program has lost the momentum it gained following the 2007 season.
