I really hoped and expected a top notch mid major OC or a P5 QB coach to take the OC job. Diaco, as a young DC turned HC, could offer a lot of freedom to an OC and give that person a chance to shine. Plus, there is an incumbent QB that shows a lot of promise. I expected to get a lot of interest for that position.
Cummings put up over 30 points just twice last year, against two of the worst teams in FBS. CMU got held to 27 by Western Michigan, one of only 3 teams that WMU held under 30 points last year. I know he had a good 2012, but that was 2012.
