Ohio State (17) and Kansas (14) split the 31 possible first-place votes by coaches. The latest change at the top of the poll was necessitated after Duke was upset by ACC opponent Virginia Tech on Saturday night.
The Buckeyes (27-2) defeated Big Ten foes Illinois and Indiana rather easily in finding their way back to the top. Ohio State started 24-0 and spent four weeks at No. 1 earlier this season before falling to third. This is the 15th straight week that Ohio State has been ranked in the top three.
Kansas (27-2) remained second and trails Ohio State by only four poll points. The Jayhawks head into the final week of the regular season in a first-place tie with Texas in the Big 12, though Texas won the teams' lone head-to-head matchup in January.
Beyond the top three, there was some eye-opening moving and shaking in the rankings underscored by St. John's and its 10-spot rise to 15th, and one-time Final Four participant George Mason joining the rankings at No. 25.
Behind All-American guard Jimmer Fredette, BYU (27-2) continues to capture the nation's interest with its climb through the top 10. This week's push came via the Cougars' second victory this season over San Diego State.
Duke (25-4) fell from first to fourth and Pittsburgh (25-4), coming off Sunday's overtime loss to Louisville, actually moved up one spot to fifth.
Even without senior forward Robbie Hummel (torn ACL), Purdue (24-5) continues its strong season by moving to sixth from eighth in the rankings. Notre Dame (23-5) jumped two spots to No. 7, Texas (24-5) fell three spots to eighth, San Diego State (27-2) fell five spots to ninth and Wisconsin moved from 12th to round out the top 10.
The second 10 kicks off with a Big East punch -- Louisville (22-7) at No. 11 and Syracuse (24-6) at No. 12, with the Orange squeezing the competition with an eight-spot jump.
North Carolina (22-6) also made a healthy move of six spots to 13th. After the Tar Heels, it was Florida (22-6) at 14th, the Red Storm (19-9), Connecticut (21-7), Georgetown (21-8), Arizona (23-6), Villanova (21-8) and Vanderbilt (21-7).
Completing the Top 25 are Utah State (26-3), Texas A&M (22-6), Kentucky (20-8), Missouri (22-7) and George Mason (25-5).
In The Associated Press media poll, its 65 possible first-place votes were divided between No. 1 Ohio State (45), No. 2 Kansas (14), No. 3 BYU (five) and No. 4 Duke (one).
