The top two teams in the AP Top 25 men's college basketball poll remained unchanged Monday with UConn and Purdue holding steady at No. 1 and No. 2 for a fifth consecutive week, but a chunk of the rankings saw a shakeup after four of last week's top-10 teams and 17 ranked teams in total took at least one loss in a chaotic week. 

The biggest beneficiary of the chaos was Marquette, which rose up three spots to No. 4, while Iowa State leapt four spots and snuck into the top-10 at No. 10.

Marquette jumped past Kansas, North Carolina and Tennessee, all of which took one loss last week, in its appearance back into the top-five of the AP poll for the first time since Week 4. The Golden Eagles held off a hungry St. John's team at home Saturday to win their seventh consecutive game after opening the 2024 calendar year with an 0-2 record.

Arizona also moved up three spots and rejoined the top five — at No. 5 — for the first time since Week 8. After climbing to No. 1 in the AP poll earlier in the season, the Wildcats fell to as low as No. 12 before a big week with wins over Utah and Colorado propelled them back into the top five. They've won seven of their last eight games in Pac-12 play and are one game up in the conference regular-season race.

Elsewhere in the AP poll, MVC-leading Indiana State appeared in the rankings for the first time since the Larry Bird days in the late 1970s. The Sycamores ended their four-decade-long drought with an appearance at No. 23 in the poll this week following wins over Valpo and Missouri State to improve to 13-2 in MVC play and 22-3 overall..
