I won't guess who but I will say that if it were to happen it would be in the semi-final game. I have a theory about that. UConn has played in 12 final fours in the last 15 years. They won 8 NC's and lost 4 times. All of the losses came in the semi-final game, three times to Notre Dame and once to Stanford. And as we all know, UConn is undefeated in the NC game. My theory is that to beat UConn a team needs a week to prepare, and a coach who is a great strategist. UConn is never a mystery as to what they will do. Geno is a coach who doesn't come up with novel plays or gimmick defenses. You know what they will do and Geno dares you to stop it. McGraw and Vanderveer have each done it. But in a national final UConn's opponents have essentially one day to get ready and no one has managed to accomplish that trick.
So if you want to beat UConn, catch them in the semi-final but keep in mind that the last 3 teams to do it lost the final.
Geno has also said that he has taken teams to the final four that were not ready to win a national championship, but he has never taken a team into the NC game that wasn't ready to win it.
If you look at the teams that lost the semi-finals since 2000:
2001 - reliant on a freshman DT after injury to two senior AA players
2008 - reliant on freshman Maya and Sophomore Tina (who had yet to get it) after senior Mel and junior Kalana go out with injuries
2011 - reliant on freshman Bria and Stef and Soph Faris after CD is lost during the summer and Walker transfers mid season
2012 - reliant on freshman KML and sophs Bria and Stef
2001 stands out as a year where the majority of starters were upperclassmen even after the injuries, and Geno has said that that loss is on him - the one that got away.
We always look at what DT did in 2003 as being amazing, because she took this very young team all the way, but she had a lot of help from two 3rd year players Maria and Jessica Moore who never get enough credit. That team had three players starting who had already both lost and won at the final four (Jessica wasn't actually playing in 2001, but she was a red shirt who experienced that year emotionally.) DT was the reason they won, but without MC and JM she couldn't have done it.
