Throughout his tenure at Michigan, Jim Harbaugh has tinkered with his coaching staff.
He has cycled through 29 assistants and rearranged the organizational structure, shifting responsibilities and titles from one year to the next.
At times, he has assigned one individual to oversee multiple position groups. In other instances, he has divvied up those duties between two people, and reallocated resources in different areas.
But as Harbaugh has repeatedly reconfigured the personnel framework below him, he has never completely removed himself from the finer aspects of Michigan's operation. His willingness to delegate has only gone so far, and the offense remains in his sphere of focus.
