At least two of the nation's best NCAA basketball teams will see their undefeated 2024/25 campaigns end this weekend, when a pair of cutthroat college clashes tests the limits of four championship contenders.

First, No. 6 Notre Dame will visit No. 3 USC on Saturday, before No. 1 South Carolina takes on the Trojans’ crosstown rival No. 5 UCLA on Sunday.

Saturday's NCAA showdown features superstar sophomores

All eyes will be on preseason All-American sophomore guards JuJu Watkins and Hannah Hidalgo when the Irish contend with their season's first ranked opponent on Saturday.

Already a phenom, Watkins became the fastest Trojan to 1,000 career points last Friday — and she did it by a mile. The previous record-holder, legend Cheryl Miller, needed 48 games to hit the same mark.

As for Hidalgo, she's already hit the century mark across Notre Dame’s four matchups to average 25 points per game — the fifth-best offensive rate in the country.

The Irish's other secret weapon, guard Olivia Miles, is also back, returning from her February 2023 ACL tear with a vengeance in the Irish's season opener. Already averaging 18.3 points per game, Miles has also banked 27 assists over Notre Dame's four games — more than twice that of any of her teammates.

Between Hildago and Miles, plus ND's admittedly lopsided matchups so far, the South Bend squad has blasted their opponents by a 42.5-point average scoring margin this season.

It's a similar story for USC, who have been on a tear since their narrow 68-66 season-opening win over then-No. 20 Ole Miss. The Trojans thrashed their next three opponents by outscoring them by a gobsmacking average of 57 points.

The Trojans will need all that offense, plus the stylings of Watkins and All-American forward Kiki Iriafen, to handle the Irish on Saturday. Notre Dame holds the 8-2 all-time series advantage between the two teams, though they haven't squared off since 2011. Should USC emerge victorious, it will be their first win over the Irish since 2006.

Sunday puts powerhouses in the paint

The subsequent Sunday battle between UCLA and South Carolina — who set a program-record 43-game win streak on Wednesday — will likely be decided in the paint, where both team's superstars thrive.

The Gamecocks' depth keeps their stat sheet fairly balanced, making junior forward Chloe Kitts’s team-leading rates in scoring and rebounding that much more impressive.

That said, her UCLA counterpart, junior center Lauren Betts, has been dominant. By averaging a double-double across the Bruins' four tilts with 21.5 points and 11.5 rebounds per game, Betts is already sparking National Player of the Year commentary.

Both squads began their 2024/25 campaigns with tight wins, but while UCLA's came over then-No. 17 Louisville, South Carolina was nearly shocked by unranked Michigan. On the other hand, the Gamecocks are the only team to have handled a Top-10 opponent so far this season, confidently downing then-No. 9 NC State just six days after their near-disaster with the Wolverines.

Sunday's showdown kicks off a gauntlet of four ranked matchups in five games for South Carolina. Even though UCLA haven't defeated the Gamecocks this century, the Bruins are the biggest challenge to the reigning champions' undefeated streak on their 2024 docket.

Depending on which version of South Carolina shows up, a combination of the bigs and each team's overall consistency will likely determine Sunday's victor.

How to watch this weekend's Top-6 NCAA basketball games

Notre Dame and USC will tip off the weekend's matchups at 4 PM ET on Saturday, airing live on NBC.

On Sunday, FS1 will broadcast South Carolina vs. UCLA at 4 PM ET on Sunday.

South Carolina basketball has a new look for the 2023-24 season.

The Gamecocks graduated all five of their starters, including the quartet often dubbed “The Freshies.” WNBA Rookie of the Year Aliyah Boston, alongside Zia Cooke and Brea Beal, started in nearly every game since their freshman seasons, and they leave big holes to fill in their absence.

Still, head coach Dawn Staley is excited for the next group to step into the starting roles.

“It’s a totally new starting five starting from scratch, so I’m excited,” she said. “I’m excited to see how they come out and play, and what they can do when they’re put under that pressure.”

Leading the new starting five are senior center Kamilla Cardoso and junior Raven Johnson. The Gamecocks also added two key transfers in the offseason in Te-Hina Paopao and Sakima Walker.

Young talent, including Chloe Kitts and Ashlyn Watkins, also could factor in, as both have shown promise during preseason. Either way, Cardoso has been tasked with becoming a bigger leader on the team.

“Kamilla has to step into the role of being our dominant post on the inside,” Staley said. “She’s very very unselfish, and at times, much like Aliyah, she’ll pass out to people who shoot half her field goal percentage, and you can’t do that. You have to bet on yourself sometimes … We want Kamilla to be a leader.”
