The Sooners took the top spot in style, getting all 65 first-place votes from the national media panel. They are the first unanimous No. 1 since Kentucky was for 12 polls last season.
This is the sixth time Oklahoma has been No. 1, moving the Sooners into a tie for 29th place on the all-time list with Memphis, Missouri and Seton Hall. No. 1 on the No. 1 list is UCLA, which was on top for 134 weeks.
The last time the Sooners were No. 1, the top players were Skeeter Henry, Smokey McCovery and William Davis. Coached by Billy Tubbs, the Sooners lost to North Carolina in the second round of the NCAA tournament and finished with a 27-5 record.
Oklahoma is the fifth team to hold the No. 1 spot this season, joining North Carolina, Kentucky, Michigan State and Kansas.
With two members of the Big 12 holding the No. 1 spot this season, it marks the first time two teams from the same conference were on top in the same season since Kentucky and Florida of the Southeastern Conference did it in 2013-14.
Duke dropped to No. 20 in this week's poll and another loss could see the Blue Devils drop out of the Top 25.
They have the longest current streak of consecutive poll appearances at 166, a run that started with the preseason poll of 2007-08. Duke is 55 weeks shy of catching UCLA, which holds the record of 221 consecutive poll appearances from 1966 to '80.
The only other school with a current streak of more than 100 weeks is Kansas, which is at 134.
