Minnesota loses two coordinators in a day

Posted by ESPN.com's Adam Rittenberg

Minnesota lost both of its coordinators in a matter of hours today, as Mike Dunbar (offense) and Ted Roof (defense) resigned from the school.

Head coach Tim Brewster announced Roof's resignation this afternoon. Roof, the former Duke head coach who spent one season in Minneapolis, will become defensive coordinator on Gene Chizik's staff at Auburn. Dunbar will pursue other career opportunities.

I've been in touch with Brewster and he doesn't seem too concerned about having to replace two coordinators. Expect replacements to be named very soon, possibly as early as Wednesday.

Minnesota clearly is going in a new direction on offense, and Dunbar's system may no longer be the best fit. Roof looks like the bigger loss given what he did with a defense that ranked last nationally in 2007, but Minnesota has enough talent returning on that side of the ball.
