Duke's fourth straight loss Sunday was the last straw for the Blue Devils in their attempt to remain a part of the Top 25 in the ESPN/USA Today coaches' poll.
The Blue Devils (18-7), saddled with a four-game losing streak for the first time in 11 years, fell from 16th to the lead position in this week's "others receiving votes" Monday.
This marks the first time in the nine-year history of the ESPN/USA Today poll -- a span of 185 polls -- that Duke has not been ranked. The Blue Devils' No. 16 ranking last week was the lowest they had been ranked over that time (they were 15th in the second and third polls of the 1999-2000 season).
Meanwhile, Duke fell out of The Associated Press poll for the first time since the end of the 1995-96 season. The Blue Devils had been in the media poll for 200 straight weeks -- the second longest streak behind UCLA.
"If you do it for a long period of time, it means you've been good that long," Duke coach Mike Krzyzewski told AP. "We never bring it up. It's a nice stat thing."
Sunday's 72-60 loss at unranked Maryland was Duke's most lopsided defeat of the season, which sent them spiraling to a 5-6 mark in ACC play.
"Of the four games [in their current losing streak], the other three we had a chance to win," Krzyzewski said. "[Sunday], something a little more extraordinary had to happen for us to win."
Florida (23-2, 10-0 SEC) held down the No. 1 ranking in unanimous fashion Monday, receiving all 31 first-place votes and 775 points, 48 points ahead of No. 2 Ohio State (22-3). The Gators pushed their winning streak to 16 games Saturday, beating Kentucky 64-61 in front of a record crowd of 24,465 at Rupp Arena.
Beyond the Gators and Buckeyes, the top six underwent a one-spot shift. No. 3 Wisconsin (24-2), No. 4 North Carolina (22-3), No. 5 Pittsburgh (22-3) and No. 6 Texas A&M (21-3) all moved up, with UCLA dropping from second to seventh following its third loss of the season, 70-65 at West Virginia on Sunday.
Kansas (21-4), Memphis (21-3) and Nevada (22-2) rounded out the top 10, with the Tigers moving up from 10th and the Wolfpack joining the first 10 from 11th.
Washington State (21-4) continued its climb up the rankings, checking in at No. 11 (up three spots) after victories last week over Stanford and Cal. Butler fell three spots to 12th and was followed by Marquette, Air Force, Southern Illinois, Georgetown, Oregon, Kentucky, Indiana and Oklahoma State.
Boston College, at No. 21, was one of four teams to enter the rankings this week, joined by the Mountaineers at 22, Arizona at 24 and Virginia Tech at 25. USC fell to 23rd after checking in tied at No. 21 last week.
Joining Duke in the list of unranked teams in this week's poll are Alabama (19th last week), Notre Dame and Texas.
