I've seen a lot of discussion in the past 24 hours about whether Michigan should hire a full-time quarterbacks coach instead of asking offensive coordinator Al Borges to do double duty. I have disagreed with that notion ever since it was mentioned in the first place (all the way back during the 2011 season), and a little bit of research today reinforces my opinion. An offensive coordinator can do just fine as the quarterbacks coach. The coordinating is done in the office, during meetings, at home, etc. The game plan and play installation is done with the other coaches, who are and should be trusted with implementing the plays. If the position coaches can't be trusted to install the offense correctly, then those position coaches need to be replaced. The only team in the AP poll's top ten without a guy who doubles as the OC/QB coach is LSU, where Steve Kragthorpe's only role is as the quarterbacks coach and Greg Studrawa is the coordinator.
