I have thought about doing this myself, but I don't have much time and if someone else wants to do it that would be great. When Hoke was hired, Brandon alluded to some research that he had done on correlation between the background of a new head coach and his winning percentage. He basically said that coaches who had previously coached in the conference, played, or recruited in the catchment area of a B10 school was much more likely to be successful than a complete outsider, and this was one of the reasons that made Hoke a more compelling candidate.
For instance, for the purposes of the study, Bo would be thought of as having a prior "connection" to Michigan because he was from the area and had coached at Ohio State, had played Michigan in games and recruited the area. But RR would be thought of as an outsider since he did not play for, or against, B10 schools that often, and did not recruit a whole lot in our backyard.
1) New coaching hires in the B10 in the last 15-20 years.
2) What percentage of them had prior connection to the school or the area, and what percentage were rank outsiders.
3) Is Dave Brandon on to something, or was he selling the new hire? Is having a prior connection to the school/area/conference a greater predictor of success than simply a coach's prior track record?
Anyway, I think this would be a cool exercise.
