Illinois is back in the college basketball top 25 rankings this week as Illinois has started 4-0 in the Big Ten.

The Illini are No. 24 in this week's Coach's Poll and No. 25 in the AP Poll. 

LSU (14-1, 2-1 SEC) rose nine spots to No. 12 following wins over ranked foes Kentucky and Tennessee, while Wisconsin (13-2, 4-1 Big Ten) is up 10 spots to No. 13 following victories over Purdue, Iowa and Maryland. The trick for the Tigers has been defense as they rank No. 1 nationally in defensive efficiency, according to KenPom.com. For Wisconsin, the formula for success has been a heavy dose of Johnny Davis. The sophomore guard is averaging 22.3 points per game and poured in a career-high 37 points in the Badgers' upset win over the Boilermakers last week.

The top four in this week's Coaches poll mirrored the AP Top 25 rankings. But the Boilermakers held on to the No. 5 spot in the Coaches poll, despite the loss to the Badgers. Kansas took a slightly further tumble in the Coaches poll than in the AP poll, as the Jayhawks fell to No. 9 after losing at Texas Tech on Saturday. The Red Raiders jumped six spots to No. 19 following the impressive win over the Jayhawks.

As for No. 1, the coaches were unanimous yet again that Baylor is the nation's No. 1 team.

Duke took its first loss of the calendar year over the weekend in a stunning 76-74 defeat to Miami, making it one of the most high-profile fallers in Monday's updated AP Top 25 poll. The Blue Devils came in at No. 8 on the heels of the loss, its first at home since February of last season. It's the first time since Dec. 13, 2021, Duke is not ranked No. 2 in the AP Poll.

The shakeup at the top wasn't exclusive to Durham, either, as Purdue, which had been ranked No. 3 for a month, also took a loss last week in 74-69 fashion to Wisconsin. The Boilermakers fell only four spots to No. 7. Kansas, another top-10 team from last week, also took a loss but fell only three spots from No. 6 to No. 9.

It wasn't all tumbling for teams in this week's poll, though, as Wisconsin made the biggest leap among 12 teams that moved up with a 10-spot leap from No. 23 to No. 13. LSU came in with the second-highest rise by moving up nine spots to No. 12 following wins over ranked Kentucky and Tennessee teams.

Meanwhile at the top of the poll, Baylor clung to its No. 1 unanimous ranking by receiving all 61 first-place votes. However, the top-five got a complete makeover with Gonzaga moving up two spots to No. 2, UCLA moving up two spots to No. 3, Auburn climbing five spots to No. 4 and USC moving from No. 7 to No. 5, the Trojans' highest ranking since they were No. 5 in December 1974.
