From what I've heard, this coming from a former player of three years, under Coach Roof at Georgia Institute of Technology, is that he is a Really Good Recruiter, a Great Coach, and even a better Man. The guy said that to give you an idea of what Coach Roof is like on the football field, think Coach Muschamp.....only 10 years older and wiser (I think he means, he's not going to be bat shit crazy, all of the time).
I think this is a Great hire (read; not as big of a "Splash" as Coach Malzahn, but a pretty big "Splash" none the less) and will definately help Coach Chizik, so that he won't have to worry about the defense.....All of the time, meaning that, he knows it'll be in great hands when he needs to do his Head Coaching duties.
My only question is, what position will he coach or will he be just the DC leaving the DL and DB positions open for coaches to be named, possibly tonight or tomorrow?
