Roof, Dunbar resign from Gophers staff

Minnesota's coaching staff will have a vastly different look for the 2009 season.

Head coach Tim Brewster on Tuesday announced the resignations of offensive coordinator Mike Dunbar and defensive coordinator Ted Roof.

Roof will take a the same position on Gene Chizik's staff at Auburn, while a news release said Dunbar hopes to pursue other professional opportunities.

Expect Brewster to move extremely fast on naming replacements. A new defensive coordinator could be named as early as Wednesday.

Minnesota rebounded from a 1-11 season in 2007 to finish 7-6 this fall and reach the Insight Bowl. The Golden Gophers dropped their final five games after vaulting into the national rankings.

After arriving in February, Roof transformed a defense that ranked last nationally in yards allowed and set school records for futility in 2007. The Gophers led the Big Ten in takeaways (30) and produced two All-Big Ten selections before struggling down the stretch.

"Our defense improved a great deal under Coach Roof this past season," Brewster said. "Good coaches are always going to be in demand and I wish Ted the best of luck in the future."

Dunbar spent two years at Minnesota after a season at Cal and saw mixed results. Minnesota ranked last in the Big Ten in rushing this season, and Brewster shifted the run-game responsibilities from Dunbar to new offensive line coach Tim Davis after hiring Davis three days after the regular-season finale.
