The Big East has five teams in the top 10 of this week's ESPN/USA Today coaches' poll with the additions of Villanova and Georgetown.
The top five remained unchanged, with No. 1 Duke, No. 2 Ohio State, No. 3 Kansas, No. 4 Connecticut and No. 5 Syracuse all holding steady.
Duke again was a unanimous choice at No. 1, receiving all 31 first-place votes from the panel of 31 Division I coaches. The Blue Devils were also ranked No. 1 in this week's Associated Press Top 25.
For the Big East, Pitt rose two spots to No. 6, while No. 8 Villanova and No. 9 Georgetown joined the top 10 from Nos. 11 and 13, respectively.
The conference has a total of seven teams in the Top 25, including No. 20 Notre Dame and No. 25 Louisville.
Two Big 12 teams fell from the top 10 as No. 6 Kansas State dropped five places to No. 11 and former No. 9 Baylor fell six spots to No. 15. But Missouri gave the conference a second top-10 team, rising two spots to No. 10.
Unbeaten San Diego State also continued its rise into college basketball's elite, climbing three places to No. 7.
Taking the steepest plunge among Top 25 teams were Tennessee, Illinois and UNLV. The Volunteers, who beat then-No. 3 Pitt on Dec. 11, plummeted from No. 7 to No. 18 after losses last week to Oakland and Charlotte.
Illinois dropped seven spots to No. 21 after being upset by Illinois-Chicago, while UNLV fell out of the Top 25 altogether after losses to Louisville and UC-Santa Barbara.
Previously unranked Texas A&M entered the poll at No. 24.
