Lincoln Riley can’t tell you who for sure will be at quarterback for Indiana when USC meets the defending national champions this weekend. And Indiana coach Curt Cignetti has kept things pretty close to the vest over whether it’ll be Josh Hoover, the usual starter, or Grant Wilson, the seventh-year backup.

“We could spend our time speculating back and forth who it’s going to be,” Riley said. “I doubt we’re going to see some radically different offense based on who the quarterback is.”

His calm comes from the fact that under-center uncertainty is nothing new at this point for No. 18 USC. Riley has spent pretty much the entire season preparing for opponents racked by quarterback questions.

It wasn’t clear, back in Week 1, who would be under center for Fresno State. Nor was it obvious two weeks later if Rutgers was sticking with its original starting quarterback.

Oregon got only three drives out of its top passer, Dante Moore, against USC before his injury thrust No. 2 Dylan Raiola into action. And a month after that, an injury to Ohio State star Julian Sayin left USC to face his backup, Luke Fahey, whom the Trojans terrorized.

It’s still up in the air if Hoover, who came to Indiana as a top transfer, will be healthy enough coming out of Indiana’s bye. Banged up for most of the past month, Hoover was replaced by Wilson in the Hoosiers’ last game before the bye. And Wilson proceeded to bring Indiana back from the brink in an overtime win over Minnesota.

Hoover wasn’t listed with any injury designation on the Big Ten’s availability reports this week. But over his last four games, Hoover has completed only 48% of his passes; clearly, he was affected by injury.

“We’ll see how the week plays out, and we’ll see who we trot out there,” Cignetti said Monday.

Whoever plays quarterback for No. 9 Indiana will have an array of weapons at their disposal, including star wideout Charlie Becker, who’s tracking to be a top-15 pick in the 2027 NFL draft. Though, that part should be nothing new, either, given USC’s recent work against Ohio State and the presumptive No. 1 pick Jeremiah Smith.

“Real physical guy, has some great speed, a really experienced receiver,” cornerback Chasen Johnson said. “That’s going to be a great matchup.”

How well Indiana is able to move the ball could decide not just the Big Ten race but both teams’ College Football Playoff fates. With a loss in Bloomington, USC would be knocked out of contention, reigniting questions about Riley’s future. With a win, USC would be propelled into the playoff conversation.

That would leave only No. 4 UCLA — and another backup quarterback, Ty Dieffenbach — standing in the Trojans’ way.

Meanwhile, USC quarterback Jayden Maiava remains the most consistent — and healthy — passer in the conference. Even if he hasn’t seemed all that consistent — or healthy — by his standards.

“He’s in a great place mentally,” Riley said. “He’s in a great place physically right now. He’s had some bumps and bruises along the year, but right now he’s as healthy as he’s been in terms of his body feeling good. He’s ready to roll, and I think he’s gearing up to play extremely well in this last stretch.”

Quarterback Ryan Rakowski of Palos Verdes High was rolling right while being chased. Two defensive backs faced a quick decision. Stick with their receiver or come up to confront Rakowski if he decided to run.

Jalen Flowers was being covered, then saw Rakowski motion with his non-throwing hand to keep going. Soon Rakowski was firing the ball to a wide-open Flowers for a 43-yard touchdown as two helpless Mira Costa defenders gave pursuit.

It was a perfect example showing the importance of chemistry between quarterback and receiver. Of course, talent helps lead to touchdowns, but chemistry beats talent like rock beats scissors.

“I think it’s kind of easy to have chemistry with him,” Rakowski said. “He understands the game so well, understands what coverages are.”

When quarterbacks and receivers are thinking alike, magic happens.

“At the end of the day, it boils down to trust,” said Westlake coach Rick Clausen, who played quarterback as did brothers Casey and Jimmy. “Is the receiver going to be where you need him to be? Is he going to make plays for you? It’s such a reliant position. You could be gifted as a thrower, gifted as a receiver, but one without the other is pretty useless.”

The best passing duos look like they have telepathic powers with the ability to anticipate each other’s next move. That’s why quarterbacks throwing to receivers in offseason practices are valuable as each learns about the other.

“When adversity hits and the finger-pointing begins, it’s your chemistry that saves you,” Mission Viejo coach Chad Johnson said.

When St. Bernard coach Dean Herrington was throwing passes to his No. 1 target, Dale Frack, in 1981 at Hart High, the chemistry between the two was legendary.

“You know where the guy is going to be. You’re on the same page,” Herrington said.

Even though the game has evolved, with sometimes four and five receivers going out for passes instead of two, Herrington said, “Chemistry is just as important, if not more so.”

“Chemistry is higher,” Hart coach Jake Goossen said. “If you have talent but it’s not complementary , it’s not going to be fruitful. I want some talent, too, but you have to have the chemistry.”

Here are duos this season showing off talent and chemistry:

Ryan Rakowski and Jalen Flowers, Palos Verdes. Whether praying together before a game or giving high-fives after touchdowns, the Palos Verdes duo keeps producing on short slants or deep posts.

Jaden Jefferson and Quentin Hale, Corona Centennial. This duo grew up together, lived together and played together for years. Jefferson definitely knows what Hale is thinking and vice versa.

Star Thomas III and KJ Woodbury, Orange. They have combined for 16 touchdowns in nine games as juniors.

Jered Smith and Aiden Mejia, Verdugo Hills. Mejia could probably close his eyes and know exactly where Smith would be passing the ball. They have nine touchdowns together.

Grady Long and Landon Armenta, La Serna. Long trusts Armenta like he’s his brother. They’ve combined for 10 touchdowns, with Armenta surpassing 1,000 yards in receiving. They’ve been best friends since kindergarten.

Dane Weber and Chase Bonta, Chaparral. An injury left Weber on the sideline to start the season, but he’s back. Weber and Bonta have known each other since kindergarten.

Brady Edmunds and Dylin Bruce, Huntington Beach. In less than two seasons, they’ve combined for 12 touchdown passes.

Koa Malau’ulu and Kuika Moaalii, St. John Bosco. They are cousins who have been playing together since they were 10. Moaalii has nine touchdown receptions and is having a breakout sophomore season.

John David Annett and JJ Haley, Corona del Mar. Annett sometimes throws the ball up knowing Haley will find a way to catch it. Both are juniors with complete trust in each other.

Hendrix Tucker and Charles Davis, Westlake. Filling in because of an injury, Tucker, a freshman, has discovered the importance of getting the ball to Davis, who has 11 touchdown receptions.

Jordan Spigarelli and Shane McKibbin, Newport Harbor. They’ve been throwing and catching passes from each other since fifth grade and have connected for eight touchdowns this season.

Give Talon Spencer a football or a baseball and he’ll do magical things.

The two-sport standout at Capistrano Valley High has helped lead the football team to a 7-1 record as quarterback.

He has completed 69% of his passes for 1,361 yards and 14 touchdowns with only two interceptions. He also has rushed for 708 yards and 14 touchdowns.

Athleticism has helped him be a dual-threat quarterback and also succeed in baseball.

Capistrano Valley upset unbeaten Corona del Mar last week and takes on 7-1 Villa Park, which lost to Corona del Mar, in a Bravo League game on Friday.

A look at two of this week’s top high school football games in the Southland:

FRIDAY

San Pedro (6-1) at Carson (7-1), 7 p.m.

The intensity level on the field and in the stands will be something to see in this Marine League title-decider. It really comes down to the quarterback. Seth Solorio of San Pedro has 23 touchdown passes. Chris Fields III of Carson has passed for 16 touchdowns and run for 12 more . Stop Fields and everything changes. The pick: Carson.

San Clemene (7-0) at San Juan Hills (7-1), 7 p.m.

San Clemente is on the verge of a Southern Section Division 1 playoff berth but needs to win out. The Tritons’ defense will be tested by San Juan Hills receiver Luke Frith, who will have a new quarterback because of an injury. San Clemente QB Preston Beck is also hurting, with receivers Ryan Matheson and Jaxson Rex potential big-play weapons. The pick: San Clemente.

Ty Dieffenbach, a former Cal Poly and Pittsburgh signal caller, wasn’t well known among UCLA and national college football fans until last week.

Dieffenbach has been patiently waiting for his moment since he made the switch from wide receiver to quarterback as a sophomore at Agoura High.

And like subbing in to play quarterback at Autzen Stadium and leading UCLA to the biggest win of the season thus far, his football journey has never been a layup. But that’s what makes Dieffenbach’s first Football Bowl Subdivision start against Wisconsin Saturday at the Rose Bowl so special.

Dieffenbach was a wiry 6-foot-3 receiver preparing for his sophomore season in 2020 when coach Dustin Croick took over the Agoura football program.

Teams had to wipe down the balls after using them during the COVID-19 pandemic. Once players were cleared to return to practice after a long break, Dieffenbach routinely ran a route, caught a pass and threw the ball back to the start of the drill.

Dieffenbach was throwing deep passes with perfect spiral in front of Croick, who lacked a starting quarterback.

Dieffenbach agreed to switch to quarterback and committed to intense training that move required.

Croick and Dieffenbach worked via Zoom to study schemes, installations and the skills it took to play under center. What would have been a grueling process for most, was an escape for Dieffenbach, who was struggling through the most adverse time in his life — his mother’s bout with breast cancer.

“He’s a sophomore. His mom was just diagnosed with breast cancer. So you have a kid that’s going through that, and the quarterback stuff was his outlet, going through the hardest thing that he’s been through off the field and something super personal,” Croick said. “Football was his medicine at that time, where it wasn’t as serious as what he was going through.”

Through it all, Dieffenbach learned how to be a quarterback and a leader. After going 7-3 and breaking the school’s single season touchdown passing record Croick once held, all of the team’s star players graduated.

And Dieffenbach, who was racking up college offers, was left with a depleted roster and a grim senior season outlook. But while top-tier high school programs tried to lure him away, it was never a question.

It was always Agoura.

“He’s getting calls left and right from other schools to transfer to big time schools that are in our area. And I remember the conversation with his dad and him. I told him if you’re going to leave, you’re still my boy. I still love you, and I get it,” Croick said. “And he’s like, absolutely not. I would never leave, because I’m Agoura. I’m A-Town, and I’m here. And to be honest, from my perspective, back then he should have left. But that’s the type of kid he is.”

Despite a 1-9 record and a knee injury sustained in Week 1 that kept him out of the rest of the season, Dieffenbach’s loyalty never wavered, and the Calabasas product was rewarded with a late offer from Pittsburgh, making him one of the first Power Four football players out of Agoura in more than a decade, Croick said.

After not seeing any action as a true freshman, he was frustrated by the lack of playing time but stayed the course, working to see the field the following season. However, after offensive coordinator Frank Cignetti Jr. was fired following a 3-9 season, his outlook at Pitt went from bad to worse.

New offensive coordinator Kade Bell wanted Dieffenbach to make another position switch, this time from quarterback to tight end.

Dieffenbach’s loyalty was tested a second time.

Take a leap of faith and leave Pitt after two seasons without playing, or stay at a program and a school where he felt comfortable.

“It was very hard for him to leave Pitt because he didn’t want to. He felt good there. He had really good friends there. But you can’t control a new offensive coordinator. You can’t control them wanting to do a position change or anything like that,” Croick said. “He just believed in himself to play quarterback. He said, ‘I want a shot at playing quarterback. If I don’t ever do that, I won’t know, so I need to do it.’”

Dieffenbach transferred to Cal Poly. After winning the starting job during preseason camp, he finally had the chance to see the field at the college level.

But injuries altered his season, consistently playing at less than 100%, missing time and never really finding a groove.

“He got hit in the back, and there were some issues there, bruising and pain, and that was a lot to have to fight through,” former Cal Poly head coach Paul Wulff said. “When you have an injury and you’re playing and you’re sore, it affects you. It’s not that easy, so he had to overcome that, which was hard for him. But he kept plugging away at it, and he finally got a little bit better and got a little more confident, and the pain wasn’t as much, but it lingered all season for him.”

And after a 4-8 season, Wulff left Cal Poly and Dieffenbach faced another crossroads.

It was not until new UCLA coach Chesney and offensive coordinator Dean Kennedy took over the Bruins that a new opportunity arose. He decided to join the UCLA roster with no guarantee he would earn snaps at a school with an established starter and a returning backup.

He earned the respect of his UCLA coaches and teammates, who were not surprised by how Dieffenbach responded when Nico Iamaleava was injured during a top 25 game at Oregon.

After leading the Bruins to their first win at Autzen Stadium since 2004, Dieffenbach earned the right to replace injured Iamaleava in the starting lineup.

“He’s been able to withstand some difficult times of not playing at Pitt or getting injured at Cal Poly. At the end of the day, he believes in himself,” Croick said. “Even at Pitt, I told him you’re going to get your shot. You just got to stay locked in. He never wavered. If you go to his time at Pitt, it was super important for where he is right now.”
