If I had to put potential candidates into tiers, I would categorize them as the following:

Dream Candidates
UConn - Football and membership in the AAC will continue to be a big question mark; Shares past conference affiliation w/ VU, GU, SJ, SH and PU; regional fit.

Serious Candidates/Peers
Saint Louis - Institutional fit; strong new media market; peer in academics; athletic program structured like other BE members;
Dayton - Institutional fit; strong fan base; peer in academics; athletic program structured like other BE members; Xavier might block them;

Wild Cards
Davidson - Strong men's basketball program; new market in North Carolina; Private Liberal Arts College; Small enrollment;
Richmond - Huge endowment; Private university; nice facilities; Lack of past success in men's basketball is a concern; however resources will always be there.
VCU - Public university; strong commitment to men's basketball; great facilities; strong academics; Would likely only be added if paired with a UConn;

Remote Long-term Candidates
Duquesne - Institutional-fit; big urban location (Pittsburgh); poor commitment to men's basketball; lower endowment;
Fordham - Institutional-fit; strong academics; big urban location (New York); poor men's basketball program; small arena;
St. Bonaventure - Institutional-fit; small rural location; poor endowment; inconsistent men's basketball program; lack of postseason appearances/success
Detroit - Institutional-fit; big metro area; poor men's basketball program;
Siena - Private school; liberal arts college; large arena; suburban campus; inconsistent men's basketball program and lack of postseason success;
