There's a new number one in men's college basketball after a week of upsets led to upheaval in the top five among the ESPN/USA Today Coaches' Poll.
Four of the top five teams lost last week, so Duke was able to slide into the number one slot in the polls by virtue of having not lost.
Duke went 3-0 in a seven day span, beating Miami and Virginia on the road before cruising to a win against Georgia Tech at Cameron Indoor Sunday night.
Ohio State dropped to No. 3 after losing on the road to Purdue 76-63—their second loss in three games after Wisconsin ended the Buckeyes' undefeated season dreams. Purdue, led by E'Twuan Moore who had a career-high 38 points, moved up in the rankings from No. 11 to No. 8 as a result.
Kansas dropped to the No. 2 spot in the rankings after losing to rival Kansas State 84-68 last Monday. The team could be in trouble headed into March after announcing that guard Tyshawn Taylor had been suspended for violating team rules.
Texas dropped from No. 2 to No. 5 after being upset by Nebraska on the road Saturday by a score of 70-67. It was the Longhorns' first loss in Big 12 play this season.
Pittsburgh fell from No. 4 to No. 6 following their 60-59 loss to St. John's at Madison Square Garden. St. John's added another impressive win to their resume. Previously the Red Storm had beaten other highly regarded teams like Duke, Georgetown, Notre Dame, and UConn. St. John's joined the Top 25 this week for the first time since the 1999-2000 season.
San Diego State moved up to No. 4 in the poll and will face off against No. 7 Brigham Young next Saturday, a game that promises to be a thriller and perhaps come close to sealing a No. 1 seed in next month's tournament for the winner.
Notre Dame and Arizona round out the rest of the Top 10.
