I explained this above, why statistically SOS is misused by most ranking systems.
So let’s compare UK and FAU opponents in order of quality:
FAU: Ariz, Illinois, TAMU, Liberty, VaTech, Butler, St Bon,
Loy-Chi, E.Mich, Charleston, Bryant, Liberty, FIU
UK: KU, UNC, Miami, St Joe, UNCW,
Penn, Marshall, UL, NM St, TAMU-Com, Stonehill
When you look at those there appears to be very little difference. We both had 6 games vs teams 150+. FAU played 2 more games, in the 50-60 range.
But that is not what you said, you claimed loss to UNCW worse than loss to Bryant, which is incorrect.
