Marisa Moseley is the 3rd assistant. She's not gonna be hired to coach Florida.
Vandy made a serious run at niele Ivey. Florida is a different animal, but wonder if they would consider her.
As for Meier, I think she's done a pretty good job in a very tough conference. And she has done coaching for USA basketball.
I think the Florida position would catch anyone's attention. The resources in the athletic department (football $$$), it's location, Gainesville rep among students are all +++ attributes. But something kept it from shining before. Doubt it was "just" the coach, so figuring out what/if any institutional/administrative issues are there would be something to address by the hiring powers that be; and, an adept coach interviewing there.
That said, the flip-side of your last two points are: would Meier and Ivey be interested in Florida (if the Gators are interested in them). Meier is in a pretty darned good position in Coral Gables, signed through 2021 and pretty much able to do what she wants. And very much embedded in the community.
Ivey is in an interesting position, as well. Save for a (very) few years away, she's been at Notre Dame non-stop as a student and now a coach. On top of that, she's a single parent whose son is very close to everyone in the coaching staff and the Joyce Center ("...it takes a department"). He was in 8th grade last year and many felt if she was going to make a break, that was the natural year. That was when she interviewed at Vandy (as you brought up) and many in South Bend and McGraw's Bench were very nervous. But White was chosen over Ivey and Banghart (a great bunch of finalists), so we got to keep our guard coach and -- perhaps even more important -- recruiting coordinator. I've always thought she'd want to find an environment similar to ND, in terms academics, athletics, support from administration, community support, etc. Most have looked at private institutions -- Vandy, Stanford, Northwestern, Duke, etc. -- but those are few and far in between. And there are those that think she's the coach-in-waiting, but there's no indication MM is ready to step down and there's a fair degree of depth in that coaching tree. So, we'll see if she heads out and where.....
