Just my $.02... I believe elite is more expansive than a 1 game loss. I think to be elite you need to go back 5-7 years and look at the history of each program and see who has performed well in that time frame. Then you need to look at who's performing well now. Then you need to look at how those teams are recruiting over the next few years.
Going back to 2010, NC winners have been UCONN (5), Baylor, and aTm
Final 4's have been UCONN (7), ND (5), Stanford (4), Baylor (2), Maryland (2), and 1 each for aTm, L'ville, Washington, Syracuse, South Carolina, Oregon State, Cal, and Oklahoma.
This is NOT in order, but I believe the elite teams in WCBB are:
UCONN - far and away the pinnacle of WCBB
Baylor - ND has more FF's, but less talent at the moment IMHO. They also continue to recruit at an elite level.
Notre Dame - 4 final 4's in 7 years - that makes them elite. They continue to recruit at an elite level as well.
IMHO those are the elite of the elite. The next tier IMHO is
Stanford - I left them off because while they are percolating around the top 10, they don't have "great" classes on the horizon and I don't see them as a final 4 threat in the next few years
Maryland - Left them off because they are close but no cigar. They need more final 4 consistency and appearances in NC games to bump up
SC - Same as Maryland. For all their talent, 1 final 4 in the last 7 years does not make a team elite.
There's really no one else "worthy" IMHO of making the list. Individual teams may have a great recruiting class, may land a top 5 player or 2, but none of them do it consistently. Don't get me wrong - there are a lot of really good teams behind that lists of 6 I threw out there, but just not elite. Florida State, Texas, UCLA, L'ville, OSU, and Duke all seem to be recruiting well and should stick around the top 10 for the next several years.
I question whether teams like Mississippi State, Washington, Oregon State, Syracuse, Miami and NC State can continue to be top 15 threats, or if their recruiting will fall off after stars leave. And then there's Tennessee - good recruiting classes the next 2 years, but they've done so much less with more that it's hard to know if the new kids will be any help at all...
