If your a Michigan fan, you might wonder why I would start a post with the former DC from Oregon who just left his role. Jim and Jimmy are buddies and have coached together. There was a strong possibility Jim Leavitt could have been Michigan DC's before Don Brown was hired. At that time he was doing a really good well as the DC at Colorado and Willie Taggart hired him at Oregon. As we know, Willie is part of Harbaugh's coaching tree.
The rumor mill is that Leavitt was not getting along with new Oregon head coach Mario Cristobal and both sides decided to move on.
