But there needs to be more than that, variables such as returning yards and other measures of returning quality players need to be used. UW lost 3 first round picks + their QB. OSU has a new HC + lost Mannion. UVA has consistently recruited well under London, who went 5-7 last year and 2-10 the year before. TT went 4-8 last year...with wins over Central Ark, UTEP, KU, and ISU, so while their record was better, that's a terrible win list (and yes, it would be for CU as well).
Considering the games we played against UW, Cal, and OSU just from the list I originally used, and what we return vs what those teams lose, it's tough to believe they are that much better than us. There may be a gap, but I don't think it's that big given the on-field performances against them.
