Trent

“Touchdown Trent Mosley.”

It’s understandable that the P.A. announcer at St. John Bosco High on Friday night misspoke after seeing Mosley’s brother, Grant, catch a 49-yard touchdown pass for Santa Margarita and run like Trent in a showdown game between the No. 1 Eagles and No. 2 Braves.

“Pretty good,” Trent, USC’s star freshman receiver, said on the sideline when asked about Grant’s touchdown. “He’s healthy.”

As if unbeaten Santa Margarita (8-0) didn’t have enough weapons, the return of Grant Mosley after two seasons of dealing with a shoulder injury means it’s time for opponents to start feeling very uncomfortable.

“I’m back,” Grant announced afterward.

Santa Margarita won its 15th consecutive game in defeating St. John Bosco 21-7.

“He looked great,” coach Carson Palmer said.

“We knew when as he got healthier, he was going to be a threat,” St. john Bosco coach Jason Negro said. “He’s a dynamic player like his brother.”

The touchdown pass happened during a trick play, in which quarterback Fletch Palmer handed the ball to Adrian Petero, who lateraled the ball back to Palmer, who threw a perfect spiral down the middle to Mosley. That play was Santa Margarita royalty at its best — a Mosley catching a touchdown pass from a Palmer, the son of the head coach.

It gave Santa Margarita a 21-7 lead in the third quarter.

“What a pass,” Carson Palmer said. “What execution. What protection.”

Santa Margarita came up with two interceptions in the first half leading to two touchdowns and a 14-7 halftime lead.

After St. John Bosco (6-2) had taken a 7-0 lead on a 28-yard touchdown catch by Kuika Moaalii, sophomore Rayshawn Brandon picked off a pass by quarterback Koa Malau’ulu, who was rolling to his left under pressure, and returned it 51 yards for a touchdown. Then Ca’ron Williams came up with another interception deep in Braves territory, leading to a one-yard touchdown run by Petero.

At the end of the half, Jaion Smith of Santa Margarita deflected a possible third-down touchdown pass in the end zone and Jake Martin followed by blocking a St. John Bosco field-goal attempt.

If anything was learned about Santa Margarita last season in its first year under Palmer, it’s that the Eagles have one of the best coaching staffs in the state and keep improving each week. By the end of the 2025 season, Santa Margarita was 35 points better than its closest opponent.

Could a similar situation be occurring now?

“I just feel we have the best staff in the nation,” Grant Mosley said. “So every week, we’re just developing. And we’re still not at our highest state. Once we get to the playoffs, that’s when we’ll be at our best.”

With Trinity League wins over St. John Bosco and Mater Dei, the Eagles have moved into the driver’s seat to win the league title.

Before the game, Carson Palmer was walking around the field feeling excited and confident.

“We’re ready,” he said.

He wasn’t kidding.

As for his brother getting initial credit for the touchdown, Grant said, “Oh well.”

“I’m still not even at my full state yet,” Grant said.

That’s scary coming from a brother with the Mosley genes.

Asked what the return of star freshman wide receiver Trent Mosley brought to the USC offense, Trojans quarterback Jayden Maiava kept his answer simple.

“Score touchdowns,” Maiava said with a smile after practice Tuesday.

In a massive 31-23 road win over Penn State on Saturday, Mosley did just that and more, catching nine passes for 111 yards, including a 19-yard touchdown catch to end USC’s first drive and give his team an early lead.

Mosley was a game-time decision Saturday after he missed the Trojans’ last three games with an injury, including USC’s crushing loss to Oregon in late September.

For his performance against Penn State, Mosley earned Big Ten Freshman of the Week honors, becoming the fourth Trojan to win the award this season. It was far from his first strong performance for USC.

Mosley caught 13 passes for four touchdown and 255 yards in his first three college games and returned a punt for a touchdown. The only game Mosley has played for USC during which he didn’t earn at least 100 receiving was the Trojans’ win over Louisiana, during which he was injured.

“I’m just trying to do my part,” Mosley said Tuesday.

The freshman, who came to USC in the spring out of Santa Margarita High, rejoined the Trojans ahead of the Penn State game while the team faced a variety of injuries to other key players on both sides of the ball. Fellow freshman standout tight end Mark Bowman and left tackle Elijah Paige were among the Trojans to miss Saturday’s game with injuries, while defensive tackle Jide Abasiri was significantly limited.

“He’s one of our best players,” Trojans coach Lincoln Riley said of Mosley. “Getting him back has added a huge boost for us. He’s a tremendous playmaker. He’s tough to tackle after the catch. We trust him a lot.”

Now, the Trojans are in a bye week before they play at Wisconsin on Oct. 24. During the bye, the first of two for USC this season, Riley said he hopes to see his team get healthier.

Riley did not address the status of any individual players Tuesday besides saying that Bowman is “getting better,” Riley said he would not rule anyone out for the Wisconsin game. USC’s next Big Ten availability report will be released on Oct. 21.

“I’m hopeful, going into Wisconsin, that just from a whole we’ll be as healthy as we’ve been the whole year,” Riley said. “We haven’t been able to see this team quite at full strength yet from a health perspective. So, I’m kind of excited and interested to see what that would look like.”

Vlad Dyakonov bolsters Trojans

With various starters injured, younger players have filled the gaps for the Trojans.

On Saturday, freshman Vlad Dyakonov took center stage filling in for the injured Paige.

Riley on Tuesday praised Dyakonov’s performance and said the lineman didn’t know he was going to start his first college game until pregame warmups. Paige was moved to a game-time decision on USC’s final availability report two hours before the Penn State game after being listed as available the entire week beforehand.

“There’s some young people across the country that if you told them that and they were in that position in that atmosphere and environment, [they] … would be a little wide-eyed,” Riley said of Dyakonov’s debut in front of more than 114,000 fans during Penn State’s annual White Out Game. “Vlad wasn’t. Vlad was like jacked. He was ready to go.”

In an appearance on Trojans Live on Monday, Riley recalled Dyakonov boldly calling out 6-foot-5, 295-pound star defensive tackle Jahkeem Stewart in a one-on-one drill during practice and holding his own.

“I think we all knew, look, he’s not going to play perfect, but I think we all knew like he’s going to go compete his you-know-what off,” Riley said Tuesday. “Nobody doubted that because that’s what he does every day. He’s built a lot of trust in here.”

Maiava echoed Riley’s sentiment when asked about Dyakonov, praising his ability to fill in for Paige on short notice.

“What an unbelievable player,” Maiava said. “He never flinched when he went out there, and we didn’t either.”

Though Dyakonov has become known for his intensity, Trojans running back King Miller, who rushed for 102 yards and a touchdown on 19 carries Saturday behind an offensive line that included Dyakonov, said he also has a sense of humor. Asked what Dyakonov was like off the field, Miller’s first description was “hilarious.”

“It’s great to have a guy like him in this room,” Miller said.
