On3 is just different. They don't appear to rely on industry consensus at all, so the there are much more dramatic outliers.
Looking at the 2022 class they had:
Pearce - Outlier High - Nailed it
Nichols - Outlier Low - Nailed it
Josephs - Outlier High - TBD
Webb - Outlier High - Probably wrong
Williams Thomas - Outlier High - Wrong
White - Outlier High - Closer to right
In 2023:
Leacock - Outlier High - Wrong
Gibson - Outlier High - Closer to right
Weathersby - Outlier High - TBD, but possibly right
Okoye - Outlier High - Wrong
Bishop - Outlier High - TBD, but closer to right
Seems like a mixed bag to me. They have clearly been higher on Tennessee that industry average.
