Seven games pair Top 25 teams, three in the Atlantic Coast Conference; two conferences -- the Big East and Missouri Valley -- start their conference tournaments; and there are five matchups with a conference regular-season championship at stake.
Conference titles are up for grabs in 13 of 30 Division I conferences and tournament berths are still to be decided in 13 leagues. Only the Ivy League and Pacific 10 and West Coast conferences continue league play through next weekend; all other women's conferences have tournaments to determine automatic bids for the NCAA tournament, for which brackets will be unveiled Nov. 10.
Defending champion Portland (16-2-0), with a young lineup featuring six freshmen, heads into the WCC clash with Santa Clara on a 12-game winning streak, 10 of them shutouts. The Broncos (10-3-5), led by preseason All-American Leslie Osborne, are unbeaten in nine games.
The best of Sunday's Big East quarterfinals pits No. 17 Connecticut against visiting Villanova. The other games are No. 2 Notre Dame-Miami, Fla., Boston College-Rutgers and West Virginia-St. John's. Sunday's MVC quarters have Creighton at Northern Iowa and Drury at Southwest Missouri State.
No. 14 Utah meets No. 16 Brigham Young in a Mountain West Conference showdown Saturday. BYU needs to win to share the conference regular-season title with the Utes. There are also title showdowns this weekend in the Big Sky (Weber State-Northern Arizona), Big West (Cal Poly-Utah State), Conference USA (UAB-South Florida, although DePaul also could earn a share) and MAAC (Loyola, Md.-Niagara).
In the Atlantic Coast, top-ranked North Carolina, at 17-0-0 the lone unbeaten D1 squad, on Friday takes on second-place Florida State, which is ranked ninth after going 10-1-1 following a 1-4 start. No. 10 Duke plays host Friday to No. 19 Maryland. No. 6 Virginia is home to No. 22 Clemson on Saturday.
There are three big clashes in the Big 12 on Friday: No. 12 Colorado, which has clinched the conference crown, is home against No. 23 Nebraska, which the Buffaloes have never beaten. No. 11 Texas A&M and No. 21 Texas resume their rivalry at Austin. And Missouri visits Iowa State with the final conference tournament berth at stake.
In the Pac-10, there's a slim chance No. 4 UCLA could clinch the title with a win Sunday against archrival USC. The weekend's other big matchup, on Friday, has No. 18 Washington home to second-place Stanford.
