Devil's Advocate: Try to look at this from the perspective of the school administration. How much work and stress is imposed on the University to maintain a program like UConn WCBB. As fans we may only see the glitz and glamour of it all.
Maybe everything sort of settles into some sort of equilibrium/homeostasis when Geno steps away. Think of some other situations in which an iconic, hugely successful coach has left. Are the resources available to the new coach automatically the same as they were for the historically great coach? UCLA, Indiana, UNLV, Duke (when Coach K retires), Tenn, ODU, LaTech (women)
I would gather that there are built in difficulties at UConn because it does not have the conference affiliations that automatically keep it strong. Regionally too has to be a strain. Seems like UConn would naturally compete with the likes of UNH, URI, UMass, UVt.
UCLA and Indiana both had huge traditions and powerful league affiliations and they have still struggled mightily without Wooden and Knight. Gunna be interesting. Just saying, it could be possible that the University will see Geno's departure as a chance to relax a tad.
I played in HS for an iconic coach (he actually coached Big John Thompson at Carroll in DC). The HS had about 120 boys, grades 7-12. Do the math. I had 21 in my graduating class. About half went to Ivies. About a quarter were National Merit Scholars. And our hoop squad was wicked. Two years in a row, D1 recruits, UVA and Jacksonville. When Coach left the Admin could finally breathe a little and "concentrate on academics". (like they really needed to) Now they compete with the tiny Catholic/Private schools around the area that nobody's ever heard of. We used to be Washington Post Metro top 20.
