IMO keeping it in the family for the sake of keeping it in the family isn't the right way to go. UConn should hire the best coach available at that time. If he/she happens to be a UConn grad, great. If not, that's fine too.
The object is to keep the UConn WCBB team the best in the nation.
I don't disagree in theory, but
1) UConn is light years ahead of the field right now. Why choose someone from the pack to bring in their vision, which has been less successful than our current approach?
2) Don't underestimate the value of family. The connection between past players and the program has huge value to UConn. Going in house has more potential to continue that, rather than bringing in a new face who has no relationship to our past players.
3) Continuity matters. The rest of woman's college basketball will certainly, and justifiably, see Geno's retirement as an opportunity. Having Shea, for example, step into the role allows us to cournter that arguement, with a business as usual narrative.
4) While an imperfect analogy, what Kevin Ollie has done on the men's side may become the text book way to continue a legacy. He's doubled down on the UConn brand by having an all UConn family staff. It can be done.
