Michigan has fired Al Borges and replaced him with Alabama's offensive coordinator, Doug Nussmeier. Nussmeier was Alabama's offensive coordinator during 2012 and 2013 and before that he was part of Steve Sarkisian's reclamation team at Washington. Before Washington he coached one season at Fresno State and before that he coached quarterbacks for the Rams. His quarterback proteges include Marc Bulger in the NFL, Jake Locker, Keith Price, and AJ McCarron and his offenses have generally improved under his guidance.
Overall this looks like a really good hire, although it sounds like Saban brought in Lane Kiffin to advise the offense prior to the Sugar Bowl. I don't think anyone knows whether this was done because Nussmeier was interviewing for head coaching positions or because Saban had philosophical differences with Nussmeier. In any case, it sounds like Kiffin will be the new OC at Alabama and Saban was preparing Kiffin for this for some time.
Overall I'm pretty optimistic about Nussmeier. He's done a terrific job with quarterbacks everywhere he's been. Of course, at Michigan the main problem was the running game, so we'll see how well he does at recovering that project. This is a much better hire than anything Michigan fans would reasonably expect considering the current state of the program and the offensive personnel going into 2014.
