Saturday saw both of the nation's top-ranked teams -- Michigan (Associated Press) and Kansas (coaches poll) -- go down, continuing a four-week trend. Which of the upsets of No. 1 were the most surprising?
5. Indiana 81, Michigan 73 (Feb. 2) » This doesn't even qualify as an upset. Playing in basketball-crazy Bloomington on a Saturday night on ESPN against a team ranked third that opened the year at No. 1 put Michigan squarely in the crosshairs.
4. N.C. State 84, Duke 76 (Jan. 12) » Little surprise here considering the No. 20 Wolfpack were at home and loaded with frontcourt power players, presenting a daunting challenge for the Blue Devils, who had just lost 6-foot-11 Ryan Kelly.
3. Syracuse 70, Louisville 68 (Jan. 19) » There was a record crowd of 22,814 in Louisville, but this was not totally unexpected considering Syracuse was No. ?6 and had toppled a No. 1 team three other times in history.
2. Miami 90, Duke 63 (Jan. 23) »
The Blue Devils' loss to the No. 25 Hurricanes wasn't a shocker, but the margin was. It was the third largest for a top-ranked team. The last time Duke had lost by more in the regular season was 29 years ago.
1. Oklahoma State 85, Kansas 80 (Feb. 2) » Kansas had the nation's longest winning streak (18 games) and had won 33 in a row at Allen Fieldhouse. OSU was unranked and had lost four of its previous eight. Considering all that, this was the biggest upset.
