As Tennessee Titans' offensive lineman Dillon Radunz enters his fourth NFL season, he has a new position, a healthy knee and a rejuvenated mindset.

Soon enough, the 2021 second-round draft pick may have a new starting job.

"I want that (right guard) spot," Radunz said. "That's what I'm striving to do."

The many offseason changes for the Titans — new coach, new running back, new wide receivers — include various changes along the offensive line, including first-round pick JC Latham taking over at left tackle and free agent signee Lloyd Cushenberry replacing Aaron Brewer at center. The right guard battle features Radunz fighting for time against returning starter Daniel Brunskill and free agent add Saahdiq Charles.

Radunz, who started 16 games at tackle over the last three seasons, is now among several players competing for the job. That's because, after the Titans hired longtime NFL offensive line coach Bill Callahan, Radunz was given a more permanent role.

"The first time I sat down with Bill, that was the conversation we had," Radunz said. "Moving to guard and working predominantly at guard."

Working out at one position gives Radunz a singular focus, but the connection with Callahan goes far beyond just a position change.

"I'm learning a lot from Bill," Radunz said. "A lot of wisdom and experience there. He's been around the league a long time and coached a lot of great football players."

Callahan, who is coach Brian Callahan's father, landed with the Titans after a four-year stint with the Cleveland Browns.

Over his 25 years in the NFL, including two seasons as the Raiders head coach and one as the Commanders' interim coach, he's overseen the success of offensive linemen like Nick Mangold, Zack Martin, Tyron Smith and D'Brickashaw Ferguson. He was named this week the winner of the Paul "Dr. Z" Zimmerman Award, a lifetime achievement award given to assistant coaches in the NFL.

"There's so much technique to learn from him," Radunz said of Callahan. "He's got technique for every minute detail of the game. We're always learning from him, because he has so much knowledge. We're just getting better and better every day."

Dillon Radunz's healthy knee sets up successful offseason program

These first three seasons have been challenging for Radunz, especially last season, when his offseason training program was disrupted by a knee injury suffered in December 2022.

"Last offseason I was rehabbing my knee the whole time," Radunz said. "Coming into an offseason where I'm able to put on healthy, good weight. It's been a good offseason for training."

Radunz said this week he weighed 317 pounds, up from last year's playing weight of 308.

"I'll probably play around 310 or 315," Radunz said. "Strength-wise, I feel like I've put on a lot more muscle. I'm a lot stronger. My legs feel amazing compared to last year."

Despite his optimism, Radunz has work to do. Brunskill and Davis have right guard experience in the NFL, Brunskill with the San Fransisco 49ers, Charles with the Washington Commanders.

In his first three seasons with the Titans, Radunz has played more right tackle than right guard, something he sees as an advantage in the competition.

"I feel like I've put in the time, I've put in some work." he said. "There's always room to improve. (My) experience has helped me a lot, just in getting more comfortable going into each season."
