Chaos ruled in college basketball on Saturday, with No. 1 Baylor, No. 5 USC, No. 10 Michigan State and No. 12 LSU falling at home to unranked opponents to headline a list of nine teams that lost over the course of the day. The upset-filled slate reinforced just how different this season is than last, when Gonzaga and Baylor stayed atop the polls for virtually the entire season before meeting in the national championship game. Depending on how things shake out, Monday's new polls could bring us our fifth No. 1 team of the season after No. 4 Auburn stated its case with another win.

Both the Bears and No. 2 Bulldogs are great again, but the two already have more combined losses (four) than they did all of last season (three), and there are still two and a half months to go until a national champion is crowned. Baylor's assailant Saturday was an unranked Oklahoma State squad that notched its first-ever road win against the No. 1 ranked team with the 61-54 victory.

The outcome underscored just how brutal the Big 12 is, but it wasn't the only conference that saw highly ranked teams lose at home against unranked opponents.

Here are the nine ranked teams on the losing end on Saturday:

  • No. 1 Baylor lost to Oklahoma State, 61-54
  • No. 5 Southern Cal lost to Oregon 81-65
  • No. 10 Michigan State lost to Northwestern 64-62
  • No. 12 LSU lost to Arkansas 65-58
  • No. 19 Texas Tech lost to Kansas State 62-51
  • No. 20 Seton Hall lost to Marquette 73-72
  • No. 21 Texas lost to No. 15 Iowa St. 79-70
  • No. 22 Tennessee lost to No. 18 Kentucky 107-79
  • No. 24 Alabama lost to Mississippi State 78-76

Let's assess the carnage with a look at the day's winners and losers in college basketball. 

Winner: Auburn makes its case for No. 1

Auburn fell behind by 14 in the first half against Ole Miss, and the poor start briefly called into question the defensive bona fides of a Tigers squad that has been much-improved on that side of the ball. But Auburn got things in order from there and outscored the Rebels 42-27 in the second half for an 80-71 win. The victory was the 13th in a row for Auburn, which is now 16-1 (5-0 SEC) and in position to potentially be No. 1 on Monday.

The Tigers' biggest competition for the top spot will likely be No. 2 Gonzaga. The Zags crushed Santa Clara 115-83 on Saturday after throttling a quality BYU team 110-84 on Thursday. Gonzaga began the season at No. 1, however, and voters may be hesitant to elevate the Zags back to the top spot over an Auburn team that is on fire. If the Tigers reach No. 1 in the AP Top 25, it would be a first for the program.

Loser: Down goes Baylor (again)

The loss to Oklahoma State means the Bears (15-2, 3-2 Big 12) are no longer the projected No. 1 overall seed in the NCAA Tournament, according to CBS Sports Bracketology Expert Jerry Palm. They will remain one of the projected four No. 1 seeds for the time being because of an 8-2 record in Quad 1 and Quad 2 games, but the fact is that the Bears have some kinks to iron out offensively. The physicality and athleticism of Texas Tech and Oklahoma State clearly bothered Baylor's guards this week as the Bears became the first No. 1 ranked team ever to lose two home games in the same week.

Baylor shot just 25.8% from the floor in the first half as the Cowboys (9-7, 2-3) opened up a 34-22 lead entering the break. The Bears should be fine in the long run, but they'll need to find their mojo quickly as they head out for road games at West Virginia and Oklahoma next week.

Winner: Kentucky honors Joe B. Hall, rolls over Tennessee

No. 18 Kentucky played an inspired game just hours after former coach Joe B. Hall died at age 93, as the Wildcats thrashed No. 22 Tennessee 107-79. It was their highest scoring game against a top-25 opponent since 1994 and UK's largest margin of victory against Tennessee since 2010. The team's 67.9% shooting percentage was the best of John Calipari's 13 seasons as coach. Freshman guard TyTy Washington led the way with a career-high 28 points.

Hall coached the Wildcats from 1972-85, leading the team to the 1978 national championship and a 297-100 mark over his 13 seasons. Before his promotion to head coach, he spent seven years as an assistant under the program's all-time wins leader Adolph Rupp. In honor of Hall, Calipari wielded a rolled up game program on the sideline Saturday, much like Hall did during his time as coach. Calipari said he plans to do that for the rest of the season. The Wildcats also began the game in a 1-3-1 as a nod to the defense that Hall often deployed during his tenure.

Loser: Texas Tech runs out of gas

Before Baylor ever went down, Kansas State offered Texas Tech -- and the country -- a reminder of how brutal life is in the Big 12 on Saturday as the Wildcats knocked off the No. 19 Texas Tech 62-51. K-State (9-7, 1-4) entered winless in league play but outscored the Red Raiders (13-4, 3-2) 36-23 in the second half. It was Texas Tech's fourth game in eight days, and the Red Raiders must have been gassed after the expending the energy required to knock off Baylor, Kansas and Oklahoma State. 

If Kansas State is capable of beating Texas Tech by double digits and Baylor is losing at home to Oklahoma State, it just confirms that any game between Big 12 teams -- regardless of where it's played -- can swing in the underdog's favor.

Winner: Arkansas gets it done with Keith Smart coaching

Arkansas has been impossible to predict this season. It started 9-0, then lost five of six, which included an embarrassing loss to Hofstra. Then, it struck back with a 44-point drubbing of Missouri on Wednesday. So which version of the Razorbacks would show up Saturday at No. 12 LSU with coach Eric Musselman back at home due to shoulder surgery? Winning on the road against a one-loss Tigers' squad seemed like a tall order, but they got it done by closing the game on a 17-2 run for a 65-58 win.

It was a much-needed victory for the Razorbacks, who had slipped to No. 85 in the NET rankings entering Saturday's action. First-year assistant Keith Smart, a native of Baton Rouge, Louisiana, filled in for Musselman, and the former longtime NBA assistant and head coach picked up his first college win in style.

Winner: Texas A&M's gaudy record improves

Missouri's misery continued Saturday as the Tigers fell to 7-9 (1-3 SEC) after squandering an 11-point second half lead. While Mizzou's turn for the terrible following an NCAA Tournament appearance last season is an attention-grabber, the real story here may be Texas A&M. The Aggies (15-2, 4-0) have now won eight straight entering a Wednesday home showdown with No. 18 Kentucky. It's been a relatively easy schedule for the Aggies so far this season, and that gaudy record will be put to the test against the Wildcats. But they should be entering with plenty of confidence considering it's been over a month since they've lost.

Loser: West Virginia gets exposed

West Virginia entered Saturday's game at No. 8 Kansas with an identical record as the Jayhawks. Both were 13-2 (2-1 Big 12), but it was pretty clear who the better team was Saturday. On a day when the underdogs had a lot of success elsewhere in the Big 12 and around the country, the Mountaineers' defense was exposed in the Jayhawks' 85-59 victory. After going nine straight games without allowing an opponent to reach 75 points, KU scored 85 on West Virginia. 

The game was billed as a battle of the Big 12's top scorers in KU's Ochai Agbaji, who is the Big 12's leading scorer, and WVU's Taz Sherman, who is No. 2. But Sherman scored a season-low 5 points, while Agbaji went for 20. Perhaps most impressive for Kansas, though, was its interior play. Read more on that here.

Winner: Duke's frontcourt dominates

The front court tandem of Paolo Banchero and Mark Williams and Mark Williams led the way for No. 8 Duke with a combined 40 points on 17 of 23 shooting in the Blue Devils' 88-73 win over NC State. Reserve center Theo John also added 10 points on 4 of 4 shooting for the Blue Devils, who dominated on the interior as coach Mike Krzyzewski made his return to the sideline after missing Wednesday's win over Wake Forest with an illness.

Winner: Oregon is back

Oregon injected some intrigue into the Pac-12 this week during a trip through Los Angeles as the Ducks knocked off No. 3 UCLA 84-81 in overtime on Thursday and followed up with an 79-69 win at No. 5 USC on Saturday. Beating two top-five teams in a three-day span flips the script on the season for the Ducks, who were No. 91 in the NET before knocking off the Bruins.

Oregon rose 13 spots after that victory and should be in line for another nice bump after dominating the Trojans during much of Saturday's tilt. USC never led. Will Richardson led the way for the Ducks (11-6, 4-2 Pac-12) with 28 points. Oregon has made a habit of improving in the second half of the season under 12th-year coach Dana Altman, and it appears the Ducks are doing the same this season. USC (14-2, 4-2) will return to the drawing board after its second loss in three games following a 13-0 start.

Loser: Michigan State misfires

No. 10 Michigan State's nine-game winning streak came to an end Saturday, when Northwestern upset the Spartans 64-62 on the road. The Wildcats (9-6, 2-4 Big Ten) were without leading scorer Pete Nance due to an ankle injury but got 18 points from Ryan Young, who entered the staring lineup in Nance's absence.

Michigan State's Malik Hall missed a potential game-winning 3-pointer, and the Spartans' Marcus Bingham Jr. drew a foul in the ensuing scrum that gave the Spartans a chance to force overtime. But Bingham missed the front end of a 1-and-1 to doom MSU's chances. Julius Marble led the Spartans (14-3, 5-1) with 18 points on 7 of 7 shooting. But his teammates combined to shoot just 34.1%, and the Spartans totaled 17 turnovers versus just 10 for Northwestern.

"This is no surprise," Michigan State coach Tom Izzo said. "We've been living on borrowed time. There is no surprise to this. We were playing very well until we started to think we're an offensive team."

Perhaps the loss was no surprise to Izzo, but it was to oddsmakers who had Northwestern pegged as a 9.5 point underdog.

Winner: Pilots land successfully

The last time Portland won a WCC game, the first case of COVID-19 had not been confirmed in the United States. That is, until Saturday. The Pilots finally picked up their first conference victory since Jan. 4, 2020 by crushing Pepperdine 82-63. The Pilots (10-7, 1-1 WCC) are off to an impressive start under first-year coach Shantay Legans, who arrived after leading Eastern Washington to an NCAA Tournament appearance last season. Only once in the 10 seasons before Legans' arrival did Portland finish with a winning record. But the Pilots will have a shot to do it this season.

Loser: Louisville fading fast

After starting ACC play 4-0, Louisville appears to be headed nowhere fast. The Cardinals lost their third straight on Saturday with a 65-53 loss at Pittsburgh. Louisville (10-7, 4-3 ACC) shot 33% from the floor as it dropped its second double-digit game to an ACC bottom feeder in a four-day span. Pittsburgh (7-10, 2-4) entered the day ranked No. 191 in the NET. The Cardinals lost 79-63 at home against NC State on Wednesday. Given the lack of quality teams in the ACC, Louisville's ability to build an at-large NCAA Tournament resume may be shot already.

Winner: Marquette soars through controversy

Marquette began the season 5-0 with eye-catching wins over Illinois, Ole Miss and West Virginia before losing six of its next nine games to fade from relevance. But since starting Big East play 0-3 in Big East play, the Golden Eagles have been the hottest team in the conference and one of the hottest in the country.

Their winning streak reached four games Saturday with a dramatic 73-72 victory over No. 20 Seton Hall that featured a controversial ending. Marquette guard Greg Elliott drew a foul with 1.8 seconds left while attempting a shot at the top of the key while guarded by Seton Hall's Bryce Aiken. It appeared that Aiken caught an elbow to the face from Elliott on the play, but it was Aiken who was called for the foul. Elliott hit one of the ensuing free throws as Seton Hall coach Kevin Willard reacted with rage toward the officiating crew.

Controversial as the ending may have been, it goes down as another victory for first-year Marquette coach Shaka Smart The Golden Eagles are now 12-6 (4-3 Big East). Saturday's win marked the first of six straight games against Big East foes in this week's AP Top 25 for the Golden Eagles. Seton Hall (11-5, 2-4) can expect to fall from the polls on Monday.

Loser: Memphis collapses

Memphis led East Carolina 70-60 with just over two minutes remaining and appeared destined for a bounce-back victory after losing at UCF on Wednesday. Then, the Tigers collapsed in truly catastrophic fashion as ECU finished the game on a 12-1 run capped by a game-winner at the buzzer from Brandon Suggs. The Tigers (9-7, 3-3 AAC) began the season ranked No. 12 and briefly rose to No. 9 following a 5-0 start. Since then, it's been one reality check after the other for coach Penny Hardaway and a program that has nothing to show for landing the nation's No. 1 recruiting classes in both 2019 and 2021.

Building an at-large NCAA Tournament resume won't be easy for Memphis at this point since the AAC offers few chances to pick up quality wins. Reaching 20 wins for a fifth straight season seems like a more reasonable goal for Memphis than reaching the NCAA Tournament for the first time since 2014.

Winner: Awesome Auzolas

It was a rough day for ranked teams in general and a rough week for the Pac-12's powers. No. 5 USC lost its first game of the season Tuesday at Stanford, and No. 3 UCLA lost its second game of the season on Thursday against Oregon. But No. 6 Arizona quietly rose above the fray with a 76-55 win over Colorado on Thursday and an 82-64 win over Utah on Saturday.

The hero against the Utes was sophomore big man Auzolas Tubelis, who finished with a career-high 32 points on 14 of 24 shooting. Arizona is now 14-1 (4-0 Pac-12) and is the last team unbeaten in league play. The Wildcats were the third-highest ranked team in the AP poll this week, but they should be the Pac-12's highest-ranked team come Monday.
