He's already checked in with the returnees/portal players. He gave a very tepid "I hope for retention" response, which does not say much about their chances of bringing anyone currently in the portal back, let alone Kymora.
He may be respected in Virginia, but so is Vanessa Blair-Lewis at George Mason. So is Sean O'Regan at JMU. So is Erin Dickerson Davis at William & Mary. And well, so is Megan Duffy at Virginia Tech. You see where I'm going with this? He wasn't head and shoulders above any of them, and him having the UVA job now does not change that.
As for Mo, she's got her sights set on more basketball success after the team stumbled into a Sweet 16. If Roussell can't promise her at least that for her senior year, she needs to leave and not look back. TCU and South Carolina can at least offer her an Elite 8. I don't know that UCLA can, but I won't bet against Cori Close.
