I don't see any reason why UConn shouldn't consider a coach from "outside the family".
Geno does it, don't think it hurts his program.
From his bio:
"Killings, who has helped shape the Owls’ roster, directed the recruitment of unanimous First Team All-American Athletic Conference player Quenton DeCosey. Under Killings’ direction, the Owls received praise for landing two ESPN Top 100 players, Trey Lowe and Levan Shawn Alston, Jr., in the 2015 recruiting class. This helped Killings earn ESPN Honors as a Top 10 Recruiter of Non-BCS programs. In addition, in the 2013 season, Killings was invited to the NCAA’s prestigious Achieving Coaching Excellence (ACE) program, where he was put through an intensive development program for preparation of career advancement.
