Short of the Knorr tenure, Ohio Football has had some good coaching during this time window with Grobe, Solich, and Albin. If you take away the 25 years or so prior the overall history of Ohio Football is pretty respectable. Here's hoping the 70s and 80s are the forever dark ages for Bobcat football.....
Exactly. You have to be careful about selection bias when picking dates to compare. Given that we all know what were the good periods and the bad periods, it would be easy for any of us to pick dates that will show Ohio to be good, or dates which show Ohio to be bad.
Picking "30 years" conveniently omits most of the bad years, and picking, say 18 years is even better. Suppose, by "coincidence", I happened to pick 2006-2023. Then the winning percentages are:
Toledo .601
Ohio .596
NIU .589
WMU .523
CMU .511
Ball St .459
Buffalo .454
BG .441
Miami .392
Kent .359
EMU .333
AKron .286
Suppose I instead, "happened" to choose beginning of time to 2005, then you get:
Miami .639
CMU .606
BG .599
WMU .560
Toledo .550
Ball State .523
Akron .512
Ohio .488
EMU .468
Buffalo .416
Kent .391
I could get even more dismal numbers if I picked, say, the 20 years between 1986-2005. If you do this, you have be careful not to conclude too much from it because, in choosing specific dates, you have predetermined the results. I suppose you could use it to compare the coaches of that period to the historical norm for the school, if you wanted to answer the question "was Solich a good coach compared to historical norms at Ohio", but again, in framing the question, and in selecting data periods, we have predetermined the answer we will get.
