No. 12 UCLA football (5-0, 3-0 Big Ten) enters its next game against Wisconsin (4-1, 2-0) Saturday afternoon at the Rose Bowl with its highest AP poll ranking since 2022. The Bruins are set to be without starting senior quarterback Nico Iamaleava for the foreseeable future, first doing so against the Badgers. Here is this week’s scouting report from Sports editor Jacob Nguyen, who almost forgot that this is the first UCLA home game since the quarter started.

Wisconsin’s offense
Offensive scheme: Pro style
Strength: Explosive plays
Weakness: Rushing consistency
Run-pass percentage: 47% pass, 53% rush
X-factor: Colton Joseph

Wisconsin walks into Pasadena to take on a UCLA defense led by coordinator Colin Hitschler, who served on Wisconsin coach Luke Fickell’s staff for six seasons across Madison and Cincinnati.

At the helm of the visiting offense is quarterback Colton Joseph, who transferred to the Big Ten after two seasons with Old Dominion, where he competed against coach Bob Chesney’s James Madison squad.

Joseph’s first season in Power Four play has not come with the prettiest accuracy, throwing for 1,132 yards on a 56.6% completion rate – the Big Ten’s second-worst efficiency among starting quarterbacks. His 10 touchdowns on the year are offset by five interceptions – the product of inconsistent ball placement and some faulty mechanics.

However, the Newport Beach, California, local has made up for his errors with an explosive arm, capable of gaining large chunks of the field in a single play. Joseph’s career average of 8.2 yards per passing play bodes well for a receiving room that has averaged 14 yards per catch.

And when Joseph is unable to make plays in the air, his dynamic dual-threat ability continues to open up the field for the Badgers, as Joseph leads the squad with 262 rushing yards and three rushing touchdowns. The former Monarch’s comfort in carrying the ball has unlocked a heavy dose of play action for Fickell’s offense. Joseph’s mobility in and out of the pocket likely forces UCLA’s hand to deploy a downhill rushing attack that showed depth in its last game against Oregon on Saturday.

The Madison team’s run game, while largely helmed by Joseph this year, will receive further reinforcements with the probable return of running back Abu Sama III, who missed Wisconsin’s last game against Michigan State. The Iowa State transfer was second on the Cyclones in rushing yards last year, boasting 732 yards alongside five rushing touchdowns.

Sama’s return gives Wisconsin another speedy, versatile halfback who can break through tackles with adept contact balance, likely splitting reps with Darrion Dupree – the Badger’s second-leading rusher. While Wisconsin is in the Big Ten’s upper half in both rushing yards per play and per game, it has struggled to consistently string together successful drives behind an average offensive line yet to fully prove itself – tied for last in the conference with six total scores on the ground, half of which are from Joseph.

In 2026, Fickell has found much more success scoring in the air, with six different players catching a touchdown this season. Wide receiver Tyrell Henry has paced the squad with 339 receiving yards, most effectively matching up in the slot, with fellow receivers Eugene Hilton Jr. and Chris Brooks Jr. giving Joseph solid options outside.

Arguably Wisconsin’s most potent weapon has been tight end Jacob Harris, who is second on the squad with 238 yards on just 13 catches. The Bowling Green transfer is currently riding a personal hot streak, with his team-high three receiving touchdowns all coming through Wisconsin’s last three games. Harris’ strong hands and 6-foot-6 frame have made him lethal as a red zone threat and RPO target.

Wisconsin’s offense may not have the biggest names in the country – or even the Big Ten – but its 4-1 record speaks for itself. If Joseph can string together enough of the right reads to pressure the Bruins’ defense, the blue and gold may be at the doorstep of their first loss of the year.

Wisconsin’s defense
Defensive scheme: 2-4-5
Strength: Pass rush
Weakness: Turnovers
X-factor: Sebastian Cheeks

Lining up against a squad without its starting quarterback, Wisconsin’s defense has an opportunity to feast – particularly at the line of scrimmage, where it has flashed one of the nation’s most elite pass rushes.

Wisconsin has totaled seven sacks through five games, which are not numbers that jump off the board, but are indicative of game tape that shows the Badgers consistently destroying pockets and hunting opposing quarterbacks. Fickell’s defense is hallmarked by exceptional versatility, capable of exploding at the snap and making opponents scramble.

The Badgers’ defensive line is led by outside linebacker Sebastian Cheeks, who paces the squad with 2.5 sacks and two forced fumbles. Cheeks has excelled as a quicker edge rusher who can shed past blockers and pressure quarterbacks, with Wisconsin’s interior anchoring a front line that is top 25 in the country in rushing yards allowed per play.

At the center of the field is one of the nation’s best linebacker duos – Mason Posa and Cooper Catalano – that has helped supplement a pass rush that most recently forced the Spartans into a sub-.500 completion percentage. The pair have combined for 85 tackles, routinely pressuring opposing signal callers and plugging up or even deflecting short- to medium-distance plays.

Rounding out a deep defensive unit that has allowed the 15th fewest yards per game in the country is a suffocating secondary that is top-10 in passing defense. Lining up on the left is cornerback Javan Robinson, who has emerged as one of the conference’s best matchups, giving up catches just 41.7% of the time and regularly making plays on the ball.

Bryce West has also been an important name manning the nickel and lining up across slot receivers, where his aggressive play and physicality have helped create one of the Big Ten’s better third-down defenses.

As a whole, Wisconsin’s secondary is almost impenetrable when it comes to explosive plays, and UCLA will be challenged in securing first downs.

Despite their strengths, there may be some individual lapses in man coverage at times that give other teams small opportunities to make big gains. Additionally, the squad has caught just three interceptions, struggling to completely force turnovers and set up the offense with good field position.

Losing Iamaleava for what is likely the rest of the year hurts, and it’ll probably look even worse against as good a passing defense as the Badgers. Should the Bruins roll with backup senior Ty Dieffenbach as they did against the Ducks, it may take a near-perfect game for UCLA to continue its undefeated season.
