When looking at seasons ending with double-digit wins and a national ranking it is even more glaring. During that same stretch Arizona has had ONE double-digit winning season and ONE ranked season, the same with Colorado. Arizona State had four such seasons.
In comparison Cincinnati had 8 of those seasons (along with four 9 win seasons), BYU had 7 of those seasons, UCF had 6 double-digit winning seasons and five ranked seasons, Houston had 5 double-digit winning seasons with 3 of them finishing nationally ranked. Also keep in mind that besides for Cincinnati's early run in the Big East these were done in non-power conferences without power conference resources. Utah had 10 of those seasons and even then Cincinnati's run is still comparable to Utah's despite Utah spended twice as much time in a power conference as Cincinnati and Cincinnati spending more time in the AAC than Utah did in the Mountain West during this stretch.
I think the new schools going to the Big 12 will be in for an awakening as the competition will be much harder week in and week out. Don't get me wrong, the AAC was a good football conference, but clearly a step down from the P5 conferences. Part of the reason Cincinnati was so successful is that they didn't play many P5 teams. Look at the comparison of 2 schools we know well that had almost identical Sagarin ratings and ranks although one had a worse record:
Cincinnati ranked #48, Sagarin rating of 74.73, record 9-4, schedule rank = 73
West Virginia ranked #49, Sagarin rating of 74.44, record 5-7, schedule rank = 11
If Cincinnati played WVU's schedule do you think they would have finished the season at 9-4?
Sagarin schedule rank over past 10 years:
Cincinnati = 80.3 (toughest = 67)
West Virginia = 25.8 (toughest = 8)
Some other metrics:
Cincinnati record over the past 10 years against current P5 schools excluding the new additions to the Big 12: 11-12
Cincinnati bowl record over the past 10 years: 2-6
Fickell knew that repeating his performance at Cincinnati over his tenure when they moved to the Big 12 would be very difficult and decided to move on.
UCF? 11-13 against the P5 in the last 10 years.
Houston? 10-9 against the P5 in the last 10 years.
