FILM STUDY: SCOUTING THE DEFENSE UP NORTH
As a former quarterback, Jim Harbaugh has been known more for his offensive mind throughout his tenure as a head coach at the University of San Diego, Stanford, and the San Francisco 49ers. Yet his teams have always featured excellent defenses, and although he's in just his first year running the program in Ann Arbor, his unit is already playing at a high level on that side of the ball.
After taking over a group that had performed well under the tutelage of former coordinator Greg Mattison, Harbaugh kept Mattison on as defensive line coach while adding former Florida coordinator D.J. Durkin to run the unit. Durkin saw success almost immediately with his aggressive, man-to-man defense that is rarely seen at the college level due to its complexity.
Unlike the 'quarters' look that Ohio State, Michigan State, and many other college programs run that feature two deep safeties, Durkin's defense regularly lines up with only one. Often using 'nickel' personnel with an extra defensive back on the field in place of a third linebacker, the Wolverines like to line up in one-on-one coverage on the outsides, letting the free safety play center-field behind them.
Although his squad often uses personnel designed to take away the passing game, the Wolverine defense has been very good against the run this year, ranking fourth nationally in rushing yards-allowed. Linebackers Joe Bolden (#35) and Desmond Morgan (#3) lead the team in tackles, but the 'overhang' players such as strong safety Jabrill Peppers (#5) are regularly involved in stopping the run, aggressively stepping up when they read a running play.
