Davis made the NCAA tournament 70% of the time when at Iowa compared to Fran's 55%. 9 NCAA berths in 13 years vs. 8 berths in 15 years.(Technically 7, because the COVID tournament was cancelled) He also made past the first weekend of the tournament 3 times(including his last year) compared to Fran's 0 times. Better conference record as well.
You can't compare that becuase of the 2 vastly different programs at the time.
Fran stepped into a program that was Steve Prohm level bad and probably one of the worst Power 5 programs on college basketball at the time. Contrast that with Tom Davis who took over one of the most talented rosters in the country and went to an Elite 8 and Sweet 16.
You could make the argument that Davis had more tournament success, but if you take away when he had Ravelings players then all he has on Fran is the 1 Sweet 16 appearance in his final year.
They were both so close in numbers I just don't understand how you can call 1 a good coach and the other a bad coach.
They were both middle of the road Big 10 programs with a 2nd round ceiling a majority of their careers.
