CBS picking Iowa for the Final Four without discussing defense is kind of silly.
In the modern analytics era (2010-present), there has been only 1 team that defensively looks somewhat close to a Bluder team to make the Final 4, and comparing Iowa favorably to that 1 team is a stretch. Bluder's 2 best defensive teams during this era (2018, 2019) were ranked 52nd and 54th in defense (Her Hoops Stats Defensive Rating), but 45 of the last 48 Final 4 teams were ranked top 15 in defense, with 35 being top 5 defenses. (These defensive numbers are much more concentrated at the top than the men's game). The 3 WBB Final 4 outliers are Oklahoma in 2010 (defensive rank 22), Cal in 2013 (D rank 32), and Washington in 2016 (D rank 38). Perhaps Washington in 2016 with Kelsey Plum is a comp for Iowa with Caitlin Clark, but that is somewhat of a stretch comparison to Bluder's best defensive teams since 2010. (Are there pre-2010 Final Four teams to which Bluder teams compare favorably (2001 SW Missouri State? 2004 Minnesota?)?
The difficulty of making the Final Four is highlighted by the Elite Eight games involving teams that actually look like a Bluder team, who all lost badly in the Elite Eight. There are only 4 teams with a sub-40 defensive ranking to make the Elite Eight from 2010-22, none of whom made the Final 4: Dayton-2015 (D rank 42, lost 91-70); Oregon-2017 (D rank 54, lost 90-52); Iowa-2019 (D rank 54; lost 85-53); and Creighton-2022 (D rank 74, lost 80-50). These numbers highlight what a great achievement it was to make the Elite Eight in 2019.
IMO, Iowa's chances of making a credible run at the Final 4 depend on Gabe Sifuentes being right about major defensive improvement, and right about the role that Goodman, O'Grady and Stuelke will play in bringing about that improvement. Molly Davis being a defensive surprise (to me) may also be necessary.
Unfortunately, I side with BraydonRoberts5, and doubt that the bench can carry to you to a top 40 defense, when the starters can't. I also think that last year was a major defensive improvement (going from 186 to 99), and that it is athletic shortcomings that will prevent Iowa from being a top 50 defense, let alone top 30/40.
