In 2012, Cincy played #22 Rutgers and #16 Louisville. Cincinnati took Louisville to overtime and lost by three. Cincinnati lost to Rutgers by 7.
Let us look at the talent disparity: Cincinnati had a four year trailing recruiting average of 56th; Rutgers was 40th and Louisville was 49th. In other words, both teams had better talent and Rutgers had substantially better talent and Cincy played them to the wire.
If you go to 2010, Cincinnati lost to 8th ranked Oklahoma by three points. Oklahoma had a 4 year trailing recruiting average of 4th best in the nation. Cincinnati, by all accounts had a decimated roster when CBJ took over, and not adjusting for that attrition, was ranked somewhere in the lower 50s. In other words, there was a HUGE disparity in talent.
I have not gone back and looked at the recruiting averages for his years prior to coaching at Cincinnati. Looking at the schedule, though, Central Michigan lost to #2 UGA in 2008 by a score of 56 to 17. That isn't surprising because my gut tells me that talent at Central Michigan was less than at Cincy. If you look at 2011 four year trailing averages, Central Michigan averages 111th whereas Cincy was 61st. An average difference that large doesn't happen over a few years, so it would be safe to assume a similar level of talent when CBJ was coach. In 2008, Central Michigan also lost to #17 Ball State by 7. I have no frame of reference for how Ball state recruited during that time period, but they (Ball State) played well enough to be ranked #17 by going 12-2.
I don't know if this changes anyone's mind, but to me it shows a team with mediocre talent playing well above their heads. That is always a sign of a good coach, at least to me.
