The Big Ten saw an unprecedented number of coaching changes during the offseason, as three head coaches were dismissed, Wisconsin's staff lost six assistants and many other moves were made. Barring an unexpected change, only four teams -- Michigan, Michigan State, Minnesota and Northwestern -- will return their full staffs intact for the 2012 campaign.
Although the coaching carousel hasn't quite reached its end, Big Ten teams have filled all of their coordinator vacancies for the coming season. The league will have 13 new coordinators at eight different programs.
It's time to pass out quick grades for the coordinator hires (co-coordinators are graded together):
Co-offensive coordinators Billy Gonzales and Chris Beatty
Previously: Gonzales was LSU's receivers coach and pass-game coordinator; Beatty was Vanderbilt's receivers coach
Adam Rittenberg: C
Gonzales and Beatty both are strong recruiters who should help bring talented players to Champaign, but they're both young and unproven as playcallers. They should bolster Illinois' receiving corps, but I'd expect a few growing pains on game days as they adjust to bigger roles with a unit that flat-lined late in the 2011 season.
Brian Bennett: B-
Both are energetic guys who should adapt well to Tim Beckman's style, and both were considered up-and-comers. But as Adam mentioned, neither had led an offense before, so it's hard to give this too high a grade yet.
Defensive coordinator Tim Banks
Previously: Co-defensive coordinator and defensive backs coach at Cincinnati
Adam Rittenberg: A-
After a very successful 2011 season, Illinois' defense is looking for continuity and Banks can provide it. His aggressive style and pressure packages should translate well for a unit that still has a lot of talent in the front seven with linebacker Jonathan Brown, defensive tackle Akeem Spence and others.
Brian Bennett: B+
Vic Koenning declined to stay, and Jon Tenuta took the job for about 20 minutes before deciding to stay at NC State. As a third choice, Banks is a really nice hire and a better fit, in my opinion, than Tenuta would have been. After a tough first year with a Cincinnati defense lacking depth and experience, Banks did a great job turning that unit around in 2011. At Illinois, he merely needs to keep it going.
Offensive coordinator Seth Littrell
Previously: Offensive coordinator and tight ends coach at Arizona
Adam Rittenberg: B+
Littrell wasn't the reason Arizona made a coaching change in 2011, as his offense ranked third nationally in passing (370.8 ypg) and 15th in total yards (465.2 ypg). He comes from the fertile Mike Leach coaching tree and should help Indiana's offense become more balanced behind promising quarterback Tre Roberson.
Brian Bennett: A
It isn't easy to hire big-name coaches at Indiana, but Kevin Wilson got a good one as Littrell was left looking for a gig. The addition of Littrell already helped the Hoosiers land promising quarterback Nathan Sudfeld on the recruiting trail.
Offensive coordinator Greg Davis
Previously: Offensive coordinator and quarterbacks coach at Texas (didn't coach in 2011)
Adam Rittenberg: B
Davis is an experienced coach who has coordinated offenses at the highest level and won a national title at Texas. He should help James Vandenberg's development at quarterback. The concern is he has been predictable at times and had his most recent success in a spread system, which Iowa likely won't use.
Brian Bennett: C+
Davis oversaw some record-breaking offenses at Texas, but he won't have the same kind of blue-chip talent at Iowa. Then again, in Kirk Ferentz's system, he won't be asked to generate 50 points per game. He's great with quarterbacks, and Ferentz will feel comfortable with a veteran coach who'll keep things simple. But to hire a guy who'd been out of football for a year was not very exciting for a program that probably could have used a battery recharge.
Defensive coordinator Phil Parker
Previously: Defensive backs coach at Iowa
Parker knows the Hawkeyes' personnel and brings an energetic personality to the defense, but he's not the big-splash addition some were hoping for after Norm Parker's retirement. Phil Parker has coached defensive backs forever but has yet to serve in a coordinator role. It'll be interesting to see how much he actually tweaks the scheme in Iowa City.
Parker knows the Hawkeyes defense in and out, and I doubt much will change with the approach now that he is in charge. There was a curiously long time between Norm Parker's retirement and his successor's appointment, and Phil Parker has never been a coordinator before, so that brings my grade down a notch.
Defensive coordinator John Papuchis
Previously: Defensive line coach and special teams coordinator, Nebraska
Papuchis is a rising star and most likely a head coach in the near future. While I'm tempted to give him a higher grade, he hasn't been a playcaller and is just four years removed from being a football intern at LSU. Inexperience is the only main drawback here.
Like Adam said, the grade level is held down here by a lack of previous experience. But every coordinator has to start somewhere, and Bo Pelini has been really high on Papuchis, who has done excellent work everywhere he's been put to use so far. Any growing pains should be offset by the knowledge Pelini can impart as a defensive-minded head coach.
Offensive coordinator Tom Herman
Previously: Offensive coordinator and quarterbacks coach, Iowa State
Herman is regarded as a rising star and a sharp offensive mind who, with the help of Urban Meyer, will inject some life into a bland Ohio State offense. The only potential drawbacks are that he hasn't proven himself in a big-time job like Ohio State, and Iowa State's offensive numbers from 2011 don't exactly jump off the page.
Ohio State fans were probably expecting a bigger name when Meyer promised to bring in the best staff in the country. But Meyer has an eye for offensive talent and will be heavily involved in the offensive game planning himself. Though Herman hasn't done it on a major stage, he'll be working with a lot more talent in Columbus, and this grade could easily prove to be an A in the future.
Defensive coordinator Luke Fickell and co-defensive coordinator Everett Withers
Previously: Fickell was Ohio State's head coach; Withers was North Carolina's head coach
There's a lot to like about this pair, as both men return to coaching defense after being put in awkward positions last season. It'll be interesting to see how Fickell fares as the primary defensive playcaller. Withers has a few blotches on his résumé (Minnesota 2007) but brings a lot of experience to the table.
The head-coaching experience both men got last year should only help their development as coaches, and both are excellent recruiters. My only concern is whether there are too many cooks in the kitchen, but there's no reason to believe that Fickell and Withers won't get along and accept their roles. If so, this should work out really well.
Defensive coordinator Ted Roof
Previously: Defensive coordinator at Auburn (briefly took Central Florida defensive coordinator job in December)
Adam Rittenberg: C+
While I loved what Roof did at Minnesota in 2008, his exit from Auburn after some struggles there raises a few red flags. The good news is he steps into a very good situation with Penn State's defense, and he has three good assistants: Larry Johnson, Ron Vanderlinden and John Butler, two of whom (Johnson and Vanderlinden) are holdovers from the previous staff.
Brian Bennett: C
Roof has some very bright spots on his long résumé, but he's also been a serial job-changer whom Auburn fans couldn't wait to see leave town despite the national title. Bill O'Brien could have retained Tom Bradley or promoted Johnson and probably done just as well, if not better. But he has a previous relationship with Roof, so the trust factor should be high.
Defensive coordinator Tim Tibesar
Previously: Defensive coordinator for the CFL's Montreal Alouettes
Both the change and the hire surprised me a bit, and Tibesar is a bit of a wild card coming back to college football from the CFL. He knows how to face the spread offense, a primary reason Danny Hope hired him, and had some success in Montreal. But his previous FBS stop at Kansas State resulted in some struggles (117th-rated defense in 2008).
Brian Bennett: C-
If Tibesar pans out as a successful defensive coordinator, perhaps Hope will start a trend of teams looking to the Great White North for assistant coaches. I'll give Hope some credit for making an unconventional choice, but I'm a little skeptical about just how well the CFL experience will translate to college.
Offensive coordinator Matt Canada
Previously: Offensive coordinator and quarterbacks coach at Northern Illinois
Canada has extensive coordinator experience, including four seasons in the Big Ten at Indiana, but he has been primarily a spread coach in recent seasons. While he had success running a pro-style system during his first stint at Northern Illinois (2003), he'll have to make some adjustments. The good news: he inherits a lot of talent and understands his main job is to keep the momentum going.
I was surprised that Bret Bielema didn't chose someone who was a pro-style disciple through and through given his strong comments about not changing the offense much after Paul Chryst left. As Adam said, Canada knows his stuff and has done some good work as a coordinator. But anytime a coach has to adjust his style to a larger system and not the other way around creates a seed of doubt.
