Week 3 proved to be very fortunate for much of the Pac-12, and as a result, for the conference as a whole.

With big wins by Washington over No. 11 Michigan State and Oregon over No. 12 BYU, the league redeemed itself from a woeful Week 1 and now enters conference play with 5 teams undefeated and another 4 teams with 1 win.

After this week, if the Pac-12 has any fewer than 5 ranked teams, something is wrong.

Here’s one thing I learned from every Pac-12 team on Saturday …

Arizona: Passing attack deeper than Jacob Cowing, Tetairoa McMillan

So much hype went into Arizona’s 2 top incoming receivers that it completely overshadowed Arizona’s other contributors.

But Jayden de Laura had a rapport with a new crop of Wildcat targets on Saturday in a 31-28 win over North Dakota State.

In doing what Kansas, Minnesota, Colorado State, Kansas State, Iowa State and 11th-ranked Iowa could not, Arizona ended the Bison’s 6-game winning streak against FBS opponents by mixing it up offensively.

Dorian Singer, who entered the game with 96 yards on the year, had 6 grabs for 88 yards on Saturday; tight end Tanner McLachlan, who had 51 yards on 4 catches against Mississippi State last week, had another 4 grabs for 50 yards in the win.

Cowing, meanwhile, had just 55 yards in his second straight weak showing, while McMillan managed one grab for 19 yards.

Arizona State: Rush defense needs complete overhaul

Make that 22-1.

The Sun Devils reached an ignominious milestone on Saturday, becoming the first Pac-12 team to lose a regular-season game to a Mid-American Conference opponent, falling to Eastern Michigan, 30-21.

And ASU didn’t just lose, the Sun Devils completely fell apart defensively.

EMU running back Samson Evans had a career-high 257 yards on 35 carries, including 161 in the second half against an Arizona State defense that couldn’t stop chasing him all over the field.

Just how bad was this? EMU entered the game with 165 total rushing yards.

Cal: Passing game is in trouble after struggling against ailing Notre Dame

The Fighting Irish entered Saturday’s game against Cal at 0-2 and on their second quarterback after the season-ending injury to Tyler Buchner last weekend. Yet it was the Bears’ passing game that looked it was at Square One on Saturday.

Cal quarterback Jack Plummer went just 16-for-37 in the Bears’ 24-17 loss to the Fighting Irish, and his passing really melted down during the stretch, even if his legs put Cal in a good position.

Down 7 with just over 9 minutes left in the fourth quarter, Plummer had a 24-yard run to get down to the Notre Dame 40-yard line and a 16-yard run on 4th-and-8 to get to the 22 with a chance to help the Bears even the game. Then Plummer missed on 1st, 2nd and 3rd downs and was sacked for an 8-yard loss on 4th down. Crisis averted for the Fighting Irish.

Later, on Cal’s last drive of the game, the Bears drove to Notre Dame’s 32-yard line, but Plummer had an incomplete pass, took a sack, and then had a Hail Mary almost caught before it ultimately fell to the ground.

Plummer has only been average in his first 3 games with the Bears after throwing 26 touchdowns and 10 interceptions in 13 stars for Purdue before transferring.

Colorado: Buffaloes are a lost cause

Facing the national leader in both total offense and total defense, Colorado barely looked like an FBS team, much less a Pac-12 team.

The Buffaloes were almost stunning in their ineptitude against Minnesota in a 49-7 road loss. Colorado’s passing game showed an almost complete inability to move the ball down the field, with three quarterbacks — JT Shrout, Brendon Lewis and Owen McCown — combining for 10-of-24 passing for a pathetic 90 yards.

Colorado’s running game showed a little moxie with 136 yards on 34 carries and rushes of 18, 16 and 14 yards, but that anemic passing offense held the Buffaloes back. Colorado went 1-for-12 on 3rd down and the Buffs didn’t even score until their first drive of the fourth quarter.

We’re at the point where we really have to ask: Will Colorado even win 1 game this season?

Oregon: Defense toughens up against BYU

Last year, the Oregon defense was torched by the Utah running game in both the regular season and the Pac-12 title game. The Utes combined for 399 yards in the 2 wins, and beefing up the run defense was a big priority for the Ducks and new head coach Dan Lanning.

On Saturday, the Ducks shut down BYU’s ground game to the tune of 61 yards on 24 carries in a decisive 41-20 win. BYU’s best run was just 11 yards.

Oregon, meanwhile, ran for 212 yards on 44 carries, with Bo Nix rushing for 3 touchdowns as well as throwing for 2.

Nix was efficient through the air, connecting on 13-of-18 passes for 222 yards and he kept his foot on the gas pedal all game.

Oregon State: Fun begins for Beavers after big win over Montana State

The Bobcats were not exactly an impressive tune-up for Oregon State heading into the most brutal 2-game stretch in the Pac-12 this season.

A 68-28 win over Montana State is not going to set the Beavers up for back-to-back games versus USC and at Utah, no matter how good OSU looked.

And the Beavers did look good: 9 touchdowns, including 4 by quarterback Chance Nolan, and touchdown runs by 5 players.

UCLA: Pass rush on high alert after near-upset against South Alabama

Playing against arguably the nation’s easiest schedule through 2 games — with dates against Bowling Green and Alabama State — UCLA’s pass rush had been slightly underwhelming. The heralded arrival of Gabriel and Grayson Murphy from North Texas and Darius Muasau from Hawaii had Bruin fans excited about the potential of dialing up the pressure.

But the Bruins had just 5 sacks in their first 2 games — including 2 each from Grayson Murphy and Laiatu Latu — and only 1 more on Saturday in a narrow 32-31 win over South Alabama.

It’s a bad sign that the Bruins didn’t put the Jaguars away early, and UCLA actually trailed at the half, 17-13. The Murphy twins made little impact, combining for 3 tackles, and aside from Carl Jones Jr.’s sack, the Bruins had just 1 other quarterback hurry, by Muasau.

This is not the start UCLA fans wanted or expected under new defensive coordinator Bill McGovern.

USC: Williams flashes with arm, legs in big win

It’s one thing when Caleb Williams is throwing darts all over the field to a receiving corps that ranks among the best in the country. But Williams did some damage with his feet in USC’s 45-17 win over Fresno State on Saturday, rushing for 2 touchdowns in addition to throwing for nearly 300 yards and 2 scores.

Unlike the Trojans’ previous win against Stanford, USC did not check out of the game early. After managing just 6 points in the second half last week, USC put up 24 this week, including touchdowns on its first three drives after intermission.

Can you imagine what the Trojans will look like once they get it together all the way around.

Utah: Cameron Rising continues his redemption tour

The difference between Florida and Southern Utah or San Diego State is quite large.

Quarterback Cameron Rising fluctuated with the skill of his opponents as well, staying clean in a 35-7 over the Aztecs.

After throwing a costly interception in the end zone at the end of the Utes’ loss to the Gators, Rising has 7 touchdowns and zero interceptions.

Washington: Huskies make huge statement in win over No. 11 Michigan State

The hire of Kalen DeBoer by Washington during the offseason had nowhere near the fanfare of some of the other job changes in the conference or country. But the early returns are magnificent.

DeBoer’s reunion with Michael Penix Jr., his former quarterback in 2019 with the Indiana Hoosiers — where DeBoer served as offensive coordinator for a year before serving as Fresno State head coach for 2 years — has been a smash hit.

Penix was brilliant in the Huskies’ 39-28 win over No. 11 Michigan State, just brilliant. He completed 24-of-40 passes for 397 yards and 4 touchdowns, connecting near and far. Penix had completions of 54, 47, 37, 29, 27, 19 and 17 yards while connecting with 9 receivers. He found Ja’Lynn Polk 6 times for 153 yards and 3 touchdowns, including a 53-yard score.

The win was a major step for the Huskies, who will likely move into the Top 25 with the victory.

Washington State: Passing game comes alive in win over hapless Rams

Maybe it’s preposterous to call a 2-0 quarterback who pulls off an upset win at No. 19 Wisconsin underwhelming, but Cameron Ward entered the year as one of the Pac-12’s most talked-about transfers, and his play until Saturday left something to be desired.

The former Incarnate Word star had been 43-of-69 for 428 yards with 4 touchdowns and 2 interceptions in wins over the Badgers and a bad Idaho team.

On Saturday against an even worse Colorado State team, Ward took a step forward, completing 24-of-34 passes for 299 yards with 4 touchdowns and 1 interception in a 38-7 win over Colorado State.

Ward is starting to build a rapport with his top targets, connecting with Donovan Ollie and De’Zhaun Stribling for 2 touchdowns a piece.
