Road wins last week against nationally ranked opponents helped Duke and Kansas jump five places each into the top five of the ESPN/USA Today coaches' Top 25 on Monday.
The Blue Devils, who beat then-No. 5 North Carolina on Austin Rivers' buzzer-beating 3-pointer, climbed to No. 4, while the Jayhawks, thanks to a convincing win at then-No. 6 Baylor, vaulted to No. 5.
Kentucky and Syracuse held steady at No. 1 and No. 2 respectively, with the Wildcats receiving all 31 first-place votes from the panel of 31 Division I coaches.
Missouri moved up one spot, to No. 3, supplanting Ohio State. The Buckeyes fell three places to No. 6, followed by North Carolina, Michigan State, Georgetown and Baylor.
Murray State had the biggest fall in the poll, falling seven places to No. 14 after suffering its first loss of the season to Tennessee State.
UNLV jumped five places to No. 11, thanks in part to its win over then-No. 14 San Diego State last week.
Entering the poll were Gonzaga at No. 24 and Notre Dame at No. 25. Falling out were Creighton, which plunged from No. 15 with three straight losses, and former No. 21 Harvard, which suffered its first Ivy League loss at Princeton.
