I don't think staff changes matter....who would want to come and be a OC or OL coach,etc.. here with Shula as head coach...knowing that the ship is sinking. I don't think no one would take a chance on Shula, or not a Big Name cordinator..they would not take the risk. JMO
I agree with your post 100%. I feel we could have used a new OL coach 4 years ago. As long as Shula is under the gun a big name OL Coach or OC would be crazy to come here unless he was promised to be HC if things with Shula do not work out. 2 issues with that, Mike Dubose (Never should have been HC), and Bill Oliver (once we was supposedly the heir apparent he started back stabbing to get rid of Stallings.)
Mike is a great guy of integrity and appears to be a good recruiter. I do not know if his ego would allow him to do it but, imagine if he were replaced and reassigned w/in the AD for a year and then return as QB coach or recruiting coordinator.
