Michigan's Coaching Vacancy: Rich Rodriguez Should Fill It This Week

As Michigan Coach Rich Rodriguez said, this should be the week he fills the defensive coaching vacancy made when Jay Hopson left to be the Defensive Coordinator at Memphis. 

What we've learned through interviews with Rich Rodriguez and Greg Robinson is that this new coach will probably be responsible for safeties and outside linebackers.  You can hear Greg Robinson talk about the vacancy here (thanks to Michael Rothstein). 

For awhile it was thought that Corwin Brown might be added to the staff.  Unfortunately (or fortunately—depending on how you feel), Corwin Brown signed on to be an assistant coach with the Patriots.  So who will Rich Rodriguez hire?

Some stories point to David Blackwell.  He was let go from South Florida when Skip Holtz took over and he does have ties to the midwest.  Information about him can be found here on Rivals.  I don't think he'd be a bad hire, but I'm not necessarily sold on him either.  

Beyond David Blackwell though, the rumors are very quiet.  Who do you think Michigan coach Rich Rodriguez will hire to fill the vacancy?  Let's get some conversation on this started below in the comments and see if a candidate emerges.

---UPDATE---

Rich Rodriguez has promoted Adam Braithwaite, a defensive quality control assistant, to this position.
