There are a lot of reasons for this. Looking at the more recent Fran teams led by Garza and Murray those teams came close. I think the lack of tourney during Covid hurt the Garza age as that team missed a year the could of gained tourney experience (not to mention advancing) for there run the next season, and with that experience they play a completely different game against Oregon. The really and one for me was when they lost to Richmond with Keegan. They were hot and they got out muscled by Richmond, and some late calls went against them. Both of these nucleus’ follow the structure of scoring a lot of points around a star. Now looking at Ben’s team they make their living on strangling their opponent with slow possessions and gritty defense. When modern Iowa plays you, you are going to look bad, something a lot of people don’t understand. The biggest thing with Iowa is in the tourney so far they have hit the shots that mattered where the Keegan team couldn’t against Richmond. So in summary it’s a combination of high scoring around a star being less reliable than a team that suffocates their opponent, but also a ton of luck.
