Except that UCF will play a tougher schedule than Wisconsin while winning by more impressive margins. Do you put them in too?
I disagree with your first sentence.
Top 100 opponents by FPI for UCF = #41 Memphis (+27), #43 USF (Nov 24), #61 SMU (Nov 4), #62 Navy (+10), #68 Maryland (+28), #91 Temple (Nov 18), #100 Cincy (+28)
Top 100 opponents by FPI for Wisc = #24 Michigan (Nov 18), #28 Iowa (Nov 11), #37 N'western (+9), #48 Indiana (Nov 4), #56 Purdue (+8), #60 Minnesota (Nov 25), #63 Nebraska (+21), #68 Maryland (+25), #75 FAU (+17), #89 Utah State (+49), #95 BYU (+44).
The Nebraska, Maryland, FAU, Utah State, BYU group is comparable to UCF's general strength of schedule and Wisconsin beat those 5 teams by an average of 31.2 points, and all of them by at least 17 points.
I guess you could say UCF beating Maryland in College Park by 28 compared to Wisconsin beating them by 25 at Camp Randall shows that UCF is about 7-10 points better than Wisconsin by the transitive property of college football, and that the most impressive win so far by either team is the 27 point win over Memphis for UCF. That would not be close to enough to trump a win over Ohio State or Penn State though.
