rookie

Jake Slaughter’s teammates could only laugh as the rookie center was swarmed by reporters asking him questions in the Chargers’ locker room.

“I don’t think he does too good with the cameras and stuff,” Isaiah World said as he recorded the spectacle with his phone. “He’s real old school.”

Whether he minds it or not, the precocious 23-year-old is living in the spotlight. Slaughter enters the Chargers’ season opener against the Arizona Cardinals as the starting center.

The second-round pick out of Florida took over the role after Tyler Biadasz, who signed a three-year deal with the Chargers last offseason, tore an anterior cruciate ligament in practice last month.

“Jake didn’t bat an eye,” offensive tackle Rashawn Slater said. “The way he’s built … he’s not going to hesitate.”

The 6-foot-4, 308-pound Slaughter, who started 33 games at center at Florida, is ready for his moment.

“You’re kind of foolish if you go into a football season not thinking you’re going to be the guy at some point,” Slaughter said. “You got to prepare like you’re going to play every snap of every series, every game … and that’s kind of been my approach since I’ve been here.”

At the time of Biadasz’s injury, Slaughter was a leading candidate in the team’s left guard competition. But the Chargers knew from the day they drafted him that he was fully capable of playing center if needed.

“Truthfully, I was like, dude, he’s going to be able to do either one,” general manager Joe Hortiz said.

Chargers defensive end Akheem Mesidor isn’t surprised by Slaughter’s seamless adjustment to center. The former edge rusher at the University of Miami remembers Slaughter’s time at Florida well.

“When we would scout him … it was always like … ‘I don’t like him,’” Mesidor said. “But then you get to meet him in person — he’s a great guy, bro. … Nothing like we portrayed him.”

Slaughter has shown the most important trait in new offensive coordinator Mike McDaniel’s system: conviction.

Grasping all of McDaniel’s concepts is no easy feat — even if they’re all Slaughter knows at the professional level. Yet the Chargers’ newest playcaller has been impressed with Slaughter’s comprehension and attention to detail.

“You can’t really compliment him. Not because he turns it down; he’s just not interested in hearing about his good play,” McDaniel said. “He wants to be corrected, and he wants to do the job right for the team. I feel like he’s wise … where he gets that regard, respect and trust of veterans — the end-all, be-all for rookies; he understands that.”

“You can tell he’s confident out there,” offensive tackle Joe Alt added. “We trust him. He trusts us.”

Slaughter also has built trust with the franchise’s most important player: Justin Herbert.

The Chargers need to do a better job of protecting the seventh-year quarterback — and Slaughter needs to play a key role in that effort.

“He’s been awesome,” Herbert said. “He’s done such a great job of picking up the offense and playing like a veteran out there. Great to have a guy like that. He’s playing a lot earlier than I think he would have thought, but that hasn’t slowed him down.”

Slaughter credits his teammates and coaches for getting him up to speed after he was thrown into the fire.

Wide receiver Ladd McConkey said the locker room has “bought into” the Chargers’ new starting center. Offensive lineman Trey Pipkins III, meanwhile, took his praise for Slaughter a step further.

“He might be one of the smartest rookies I’ve ever seen,” Pipkins said.

Slaughter, however, earned veteran approval long before any cameras were crammed in his face. Coach Jim Harbaugh insisted he knew Slaughter was a starting-caliber player in early August.

“You know when you see it,” Harbaugh said.

But before the rookie can lose himself in any pressure or nerves on Sunday, he’s simply happy for the opportunity.

“That’s an experience I hope I’ll never forget,” Slaughter said about his upcoming NFL debut. “Something I really never thought I’d get to do growing up. It’s a really unique honor, and I’m really thankful I can be out there and play ball.”

What’s more impressive: Dylan O’Leary, the 25-year-old rookie football coach at San Dimas High, or Dylan O’Leary, the math teacher who graduated from UCLA and got his master’s at La Verne?

He’s good in both roles. San Dimas has started 2-0, with wins over Glendora (24-21) and Chaffey (44-8). His father, Tim, was a longtime baseball coach at Covina. Dylan spent four years as an assistant coach at South Hills.

He used to be a three-sport athlete at San Dimas, which has long used the Wing-T offense in football. When O’Leary was interviewed for the job, one of the first questions was, “Are you going to run the same offense?”

He was truthful in saying no.

San Dimas has switched to a spread offense. O’Leary has helped himself by adding lots of experienced assistant coaches and former head coaches.

Even though O’Leary is young, he’s earned respect in the classroom and on the field. He’s a full-time math teacher with a teaching credential. Even when he was 22 and teaching math to 17- and 18-year-olds at Chino Hills, few were skeptical about his youth.

“I’ve never really had an issue with my age,” he said.

In a time when it’s tough getting a full-time teaching job at such a young age and when coaches are mostly walk-ons, O’Leary is in position to make himself very valuable.

And, if the wins keep piling up, San Dimas might need to put a fence around his classroom so no one steals him away.
