Siena is out of the running for an at-large bid. The Saints may be ranked 36th in the RPI, but their loss at Butler last Saturday dropped them to 0--4 against teams ranked in the top 50 of the RPI. They will have to win the MAAC tournament to reach the Big Dance.... Ernie Kent has been on the hot seat before, but with the Ducks (12--14 at week's end) in last place in the Pac-10 with a 4--10 record, and with the school set to open a new arena next season, his prospects for staying in Eugene look dim.... Villanova needs to shore up its defense. Taylor King(below, 31) and the 'Cats were woeful in last week's losses to UConn and Pittsburgh. Through Sunday, 'Nova led the Big East in scoring (85.0 points per game), but it was 66th nationally in defensive efficiency.
