Purdue became this season's first unanimous No. 1 team in the AP Top 25 men's college basketball poll Monday after wins over Michigan and Michigan State last week, but chaos ensued behind the Boilermakers among other ranked teams.
More than half of the Top 25 teams lost, including second-ranked Alabama, which was routed by Oklahoma in the Big 12/SEC Challenge. That allowed Purdue to grab the remaining No. 1 votes and tighten its grip atop the poll, while Tennessee jumped two spots to second and Houston held on to third in voting by 62 national media members.
The Boilermakers (21-1) have won eight straight since a one-point loss to Rutgers on Jan. 2.
"We're the No. 1 team in the country because of how unselfish we are as a team," Purdue guard David Jenkins Jr. said. "We had a lot of people doubting us in the beginning because, you know, we may not be the most talented team or whatever, but we're close on the court and off the court, and it's really translating to how we're winning."
The Volunteers climbed to their highest perch since reaching No. 1 for four weeks during the 2018-19 season. They routed Georgia before becoming one of three SEC teams to beat Big 12 opponents Saturday, knocking off No. 10 Texas 82-71 for their fifth consecutive win over a top-10 team.
Perhaps this is the year Rick Barnes will finally get the Vols through the Sweet 16 for the first time as their coach.
"We have a chance to be as good as we want to be," Barnes said. "It's up to one thing: Are we tough enough to embrace the daily grind? And not worry about going to the Final Four or worry about going to the NCAA tournament, but can we build a team that can be successful that time of year? It starts with truly embracing the grind."
The Crimson Tide dropped to fourth after the blowout loss to the Sooners, when Alabama fell behind by 17 at halftime in an eventual 93-69 defeat. The Tide edged fifth-ranked Arizona by just two points in this week's poll.
"It doesn't have any effect on SEC standings, which is the only good thing to come out of this," Alabama coach Nate Oats said of the lopsided loss. "Hopefully we'll recover from a loss out of conference, but you know, it's not good."
Virginia was sixth and Kansas State, which rebounded from a narrow loss at No. 13 Iowa State by pummeling Florida on Saturday, fell two spots to seventh; the Wildcats will face eighth-ranked Kansas in a top-10 showdown Tuesday night.
UCLA dropped to ninth after losing to Southern California, and Texas rounded out the top 10.
Baylor continued its climb from unranked to No. 11 after wins over the Jayhawks and Arkansas. The Bears were followed by Gonzaga, Iowa State, Marquette and league rival TCU -- the sixth Big 12 team in the top 15.
Xavier, Providence, Saint Mary's, Florida Atlantic and Clemson completed the top 20, while poll returners Indiana and San Diego State joined Miami, UConn and Auburn in rounding out the Top 25.
Rising and falling
The No. 11 Bears and No. 17 Providence made the biggest leaps, each climbing six spots from last week.
"I think our defense is better. Our turnovers are better. When you don't give people easy transition baskets, now it's 5-on-5 in the half court," said Baylor coach Scott Drew, whose team had a date with the Longhorns on Monday night.
"We execute at a pretty high rate," Drew said. "It really comes down to taking care of the ball, making sure we get shots up, and when you don't make them, you've got to get rebounds. And our guys are buying into that."
Auburn took the biggest hit of those still in the poll, dropping 10 places after losses to unranked Texas A&M and West Virginia.
In and out
The Hoosiers returned to the poll at No. 22, and the Aztecs rejoined it right behind them. They took the place of Charleston, which fell out from No. 18 after losing to Hofstra, and New Mexico, which lost to Nevada in double overtime last week.
The Big 12's dominance of the SEC in the final year of their head-to-head challenge was rewarded in the poll, where the league led the way with six ranked teams, all of them in the top 15. The Big East has four teams in the poll but none higher than No. 14 Marquette, while the SEC and ACC have three teams apiece.
