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 as chaos ensued behind the Boilermakers among other ranked teams.

More than half of 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 onto 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 on 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 finally gets 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,” he 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.”

South Carolina tops women’s poll; Ohio State tumbles

It was a rough week for Ohio State, which lost all three of its games and tumbled down the AP Top 25 as a result.

The previously unbeaten Buckeyes fell from second to 10th in The Associated Press women’s basketball poll released Monday after losing to Iowa and Indiana, two top 10 teams, as well as Purdue. Ohio State fell two games back in the Big Ten Conference standings.

South Carolina remained No. 1 for the 32nd consecutive week. The Gamecocks, who were again a unanimous choice from the 28-member national media panel, have the fourth-longest streak ever atop the poll. Only Uconn (51 and 34 weeks) and Louisiana Tech (36) have had longer runs at No. 1.

Stanford moved back up to No. 2 in the poll and the Car

dinal were followed by LSU, Indiana and Uconn in the top five. LSU is the only other undefeated team in women’s basketball besides South Carolina, which visits Uconn for a top-five showdown on Sunday.

Iowa jumped out four spots to sixth with Utah, Maryland and Notre Dame coming in ahead of Ohio State. The Hawkeyes started the season No. 4 in the poll.

The Fighting Irish split a pair of games last week against ranked opponents, routing Florida State before falling to N.C. State.

“There’s a lot of parity right now, which is great, great for the game,” Notre Dame coach Niele Ivey said. “The game is growing, which is what you want. But yeah, I mean, every night, especially the ACC, the ACC is the strongest league and, you know, we have just a tough stretch every night.”

One week after falling out of the rankings, Texas re-entered the poll at No. 24. The Longhorns routed then-no. 14 Oklahoma and Oklahoma State last week. South Florida also came in at No. 25. Colorado and Illinois fell out of the poll.
