Michigan coach Rich Rodriguez has said it’s difficult to make major in-season adjustments. But that doesn’t mean he’s not looking for chances to do just that.

On Tuesday’s weekly Big Ten teleconference, Rodriguez said he’s considering moving 6-foot-5, 333-pound sophomore defensive tackle Will Campbell to the offensive side of the ball.

“He may be better suited to play guard,” Rodriguez said. "He's not playing much on defense. He's got a couple pretty good guys in front of him. I don't know if it's possible to switch and learn a position from one side of the ball to the other (for this year); that's hard to do. But we'll probably talk about him (Tuesday).”

Campbell, a consensus five-star defensive lineman from Detroit Cass Tech, has seen the field mostly on special teams, and some time for goal-line defense.

"Part of it is because (starting defensive tackles) Mike Martin and Adam Patterson are pretty good, stronger, and they're pretty active guys," Rodriguez said. "Will is working harder, getting himself in shape. He's got to get better technique-wise, getting off blocks and those kind of things.

“We're going to talk about it. He's got a great attitude, and he's working and doing everything to help the team."

Rodriguez said any position switches will likely occur soon and that he would talk to his coaching staff Wednesday about potential changes.

HELLO, BYE WEEK: One thing was clear after Saturday’s loss to Iowa, a game that left the Wolverines bewildered and bruised: The bye week couldn’t have come at a better time.

Not only will the extra week off provide players with an opportunity to heal minor injuries and study for midterms, but it will also give the coaching staff a chance to make midseason adjustments.

Rodriguez has said that some of the defense’s problems, like tackling, can be fixed on a week-to-week basis.

Other problems are beyond coaching, he said.

“Vince Lombardi could come in and not fix some of the problems on defense,” Rodriguez said at his weekly news conference on Monday.

Rodriguez’s zinger came during a discussion about the team's youth. Seven true freshmen have seen significant playing time on defense so far.

“The only way to get experience is to get experience,” Rodriguez said. “How can we limit those dangerous freshman moments?”

INJURY UPDATES: Rodriguez said Tuesday that sophomore quarterback Denard Robinson should be near 100 percent healthy for Michigan’s game against Penn State on Oct. 30. Robinson has been dealing with a nagging shoulder injury, and he left Saturday’s game in the third quarter. He didn’t return.

Rodriguez said Monday he expects defensive tackle Mike Martin and center David Molk to return from ankle injuries in time for the Penn State game, too. Running back Michael Shaw, who tweaked his knee and played sparingly against the Hawkeyes, is also expected to be healthy by Oct. 30.

Rodriguez said slot receiver Martavious Odoms’s surgery to repair a broken foot suffered against Michigan State went well. He doesn’t know how long the rehabilitation and recovery will take, though it doesn’t seem likely that Odoms will return by the end of the season.
