Purdue's hiring of defensive coordinator Donn Landholm on Monday likely marks the end to the major coaching moves in the Big Ten this year.
There have been no head-coaching changes -- Danny Hope was named Purdue's head coach-in-waiting last year -- and unless Iowa's Kirk Ferentz bolts for the Kansas City Chiefs, which isn't likely, all 11 teams will have continuity on top. But there were several key changes among coordinators and key position coaches.
Here's a summary.
Offensive coordinator: Mike Locksley left to become New Mexico's head coach. Illinois hired TCU offensive coordinator Mike Schultz as his replacement.
Defensive line: Ron Zook fired Tom Sims and hired Cincinnati's Keith Gilmore.
Offensive line: Eric Wolford left for the same post at South Carolina, and Zook hired Houston's Joe Gilbert as his replacement.
Notes: Arguably Illinois' biggest coaching move was one that didn't happen. Zook offered Penn State defensive line coach Larry Johnson the chance to be Illinois' defensive coordinator, but the ace recruiter opted to stay at State College.
Notes: Despite a 3-9 season that saw regression on both sides of the ball, head coach Bill Lynch said he didn't expect to make any staff changes for 2009.
Notes: Ferentz is being mentioned as a candidate for the Chiefs' head-coaching vacancy because of his ties to new general manager Scott Pioli, but it appears likely he will remain at Iowa for an 11th season. He will hold a signing day news conference scheduled for Feb. 4 and has talked with athletic director Gary Barta about a contract extension.
Defensive coordinator: Scott Shafer resigned and later took the same job at Syracuse. Michigan hired former Syracuse head coach Greg Robinson as Shafer's replacement.
Notes: Head coach Rich Rodriguez took his time with the search, and Robinson actually reached out to him about the defensive coordinator vacancy.
Notes: Offensive coordinator Don Treadwell was in the mix for several head-coaching spots (Miami University, Boston College) but will stay put for 2009.
Offensive coordinator: Mike Dunbar resigned Jan. 6 to pursue other professional opportunities. Minnesota hired former Denver Broncos wide receivers coach Jedd Fisch as Dunbar's replacement.
Defensive coordinator: Ted Roof resigned Jan. 6 to take the same post at Auburn. Gophers head coach Tim Brewster hired former Nebraska and Wisconsin defensive coordinator Kevin Cosgrove, who will share coordinator duties with defensive backs coach Ron Lee.
Notes: Fisch will call the offensive plays, but he must collaborate with Tim Davis, the team's new offensive line coach and run game coordinator. Davis, who replaces Phil Meyer, was hired in late November to transform Minnesota's run game and return the team to its roots as a dominant rushing attack.
Offensive line: Bret Ingalls left for the New Orleans Saints. Head coach Pat Fitzgerald told me he's not concerned about naming a replacement until after signing day, but indications are Adam Cushing, the H-backs coach and recruiting coordinator, will be promoted to line coach.
Notes: Athletic director Jim Phillips wants to work out a contract extension for Fitzgerald and likely will announce one in the coming weeks or months.
Notes: Some expected offensive coordinator/offensive line coach Jim Bollman to get the axe, and while it still could happen, head coach Jim Tressel is the primary playcaller and responsible for the unit's success. Co-defensive coordinator and linebackers coach Luke Fickell was mentioned as a candidate for the head-coaching vacancy at Bowling Green.
Notes: Penn State retained Larry Johnson despite Illinois offering more money and a coordinator position. Longtime defensive coordinator Tom Bradley also remains despite some rumors that he was a candidate for the top job at Syracuse.
Offensive coordinator: Ed Zaunbrecher was fired and replaced by Florida Atlantic offensive coordinator Gary Nord.
Defensive coordinator: Longtime Boilers defensive coordinator Brock Spack left to become Illinois State's head coach. Hope hired his former Eastern Kentucky staffer Landholm as Spack's replacement.
Running backs: Joel Thomas left for the same job at Washington, and Hope hired former Kansas State assistant Cornell Jackson as his replacement.
Offensive line: Hope handled the line in 2008 and hired his former Eastern Kentucky staffer Shawn Clark to replace him.
Special teams: Hope moved Mark Hagen from special teams to linebackers and promoted graduate assistant J.B. Gibboney to this post.
Notes: Tight ends coach John McDonnell was not retained for 2009, and a replacement hasn't been named. Terrell Williams will once again coach the entire defensive line this fall after working strictly with the ends in 2008.
Notes: After firing veteran defensive coordinator Mike Hankwitz and seeing offensive line coach Bob Palcic leave for UCLA last year, head coach Bret Bielema is keeping his staff in place despite a very disappointing 2008 season.
