Berube has a stellar won-loss record at DIII Tufts and now at Ancient Eight Princeton, one of the richest universities in the world.
But Ralph has far more experience recruiting elite D1 basketball players—at UConn, Vanderbilt and even PItt—and recruiting is the first, second and third most important coaching skill in women's college basketball.
I don't see Ralph leaving a program she personally resurrected from the dead to follow an a once-in-history god at UConn, unless the financial incentives are simply overwhelming. In addition, lots of folks, particularly southerners like Ralph, consider Nashville to be one of the most desirable cities in the country to live in.
Maybe Ralph would be somewhat incentivized to leave the badlands of the SEC for the soft grass of the Big East if success there becomes too hard for her, but that would probably mean her program is stumbling on the Via Dolorosa, in which event she would become less desirable to the UConn AD.
I've always thought Diana Taurasi would make an excellent recruiter and X/O technical coach, notwithstanding her lack of coaching experience. Her personal charisma is gravitationally attractive, like Geno's, and no one has had more experience in playing at the highest levels and for the best coaches in the world.
