So far, the women's NCAA Tournament has produced buzzer-beaters and broken bones, upsets and upstarts. Now it really gets interesting - 16 teams playing in the regional semifinals, each just two victories from a berth in the Final Four in Atlanta.

Story lines - and questions - abound.

• Can someone accomplish what never has been done: beat Tennessee in an NCAA Tournament game in Knoxville

• Does Amber Jacobs of Boston College have another game-winning shot in her repertoire?

• How long can Diana Taurasi keep carrying Connecticut?

• Will two broken bones in her face hinder LSU's quick, spunky point guard, Temeka Johnson?

The answers start coming today in the Mideast and Midwest. In the Mideast at Knoxville, Tennessee (30-4) plays Penn State (26-8) and Villanova (27-5) meets Colorado (24-7). The Midwest games at Albuquerque, N.M., have Duke (33-1) facing Georgia (21-9), and New Mexico (24-8) meeting Texas Tech (28-5).

On Sunday, Connecticut (33-1) plays Boston College (22-8), and Purdue (28-5) takes on Notre Dame (21-10) in the East Regional at Dayton, Ohio. And in the West at Stanford, it's LSU (29-3) vs. Louisiana Tech (31-2) and Minnesota (25-5), in the round of 16 for the first time, playing Texas (27-5).

"Watching doesn't even begin to compare to playing in it," Minnesota's Shannon Schonrock said.

EAST

The last four national champions are here: Purdue (1999), Connecticut (2000 and 2002) and Notre Dame (2001). Boston College has never been this far before, but the Eagles play in the Big East with UConn and Notre Dame.

MIDEAST

Penn State, Colorado and Villanova will be ready for a color other than orange and a song other than "Rocky Top" by the time this regional ends. Tennessee, a six-time national champion, is 42-0 in NCAA games at home.

MIDWEST

Sixth-seeded New Mexico drew more than 16,000 for each of its first two games, and fans will pack The Pit again for Texas Tech, the 1993 national champion. Duke's Alana Beard is still scoring and Georgia's already slim roster shrunk more when guard Sherrill Baker separated her shoulder against Rutgers.

WEST

Though they are established powers in the same state, LSU and Louisiana Tech are meeting for only the second time in 12 years. Tech has the nation's longest winning streak at 29 games. LSU is counting on Johnson's return.

Sixth-seeded Minnesota faces Texas, which has won 15 in a row. The Longhorns won the 1986 national championship.
