BLACKSBURG – Virginia Tech football is ushering in a new era under Head Coach Brent Pry, and the Hokies are already seeing the effects of his transformative vision. Pry has made headlines by bringing in NFL-caliber talent to reshape the program, with defensive coordinator Sam Siefkes at the forefront of the revamp. With a coaching career that spans the NFL, FBS, FCS and Division III, Siefkes brings a wealth of knowledge and a fresh perspective to the Hokies' defense.  

Siefkes' coaching journey began with notable collegiate stints at the University of Wisconsin in 2015, where he contributed to the Badgers' nation-leading defense, helping them rank No. 1 in scoring defense and No. 2 in total defense. As a coordinator at Wofford from 2018-2020, Siefkes’ defenses ranked first in total and rushing defense, leading the program to back-to-back Southern Conference Championships and FCS playoff appearances. Under his leadership, Wofford’s defense ranked eighth in the nation for scoring defense in 2018, helping the team advance to the second round of the FCS playoffs with a 9-4 record. 

Reflecting on his time at Wofford, Siefkes highlighted the importance of establishing solid fundamentals and building a strong defensive culture—values he aims to bring to the program.  

“The biggest thing is, if you have foundational pieces for what you’re trying to do within the culture of the defense, that kind of sets the parameters and pillars of who you want to be,” Siefkes explained. “We want to play with great effort and be violent at the point of attack. In order to play great defense, you’ve got to do those things. And, of course, we’ll be founded on stopping the run, which has always been important to me. That’s the first thing, and the rest comes as you go through the process of playing great defense.” 

That defensive mindset was reinforced during his transition to the professional level, where he spent two seasons with the Minnesota Vikings. After building stout run defenses at Wofford, Siefkes took on a new challenge in the NFL, first serving as a defensive quality control coach in 2021 before being promoted to assistant linebackers coach in 2022. In that role, he helped linebackers Eric Kendricks and Jordan Hicks combine for 265 tackles, both finishing among the league’s top 20 in that category. Hicks also ranked second among NFL linebackers in passes defended. 

Siefkes’ time with the Vikings also provided the chance to learn from legendary defensive coach Mike Zimmer, who became a key mentor in Siefkes’ development. 

“Zimmer was really influential in opening my eyes to a different world,” Siefkes said. “Probably the best third down guy I’ve ever been around, he taught me different ways to attack protections and offenses. That was really beneficial for my growth and getting to a spot like this.”

Siefkes’ time in Minnesota not only expanded his defensive knowledge but also paved the way for his next opportunity in the NFL. Following his stint with the Vikings, he most recently spent two seasons as the linebackers coach for the Arizona Cardinals, where he played a pivotal role in developing standout talent on the defensive side of the ball. During his tenure, he worked with linebacker Kyzir White, who finished 15th in the NFL with 137 tackles in 2024, and worked closely with safety Budda Baker, who earned Pro Bowl honors after ranking second in the league with 164 tackles. 

Now, as Siefkes transitions to working with a defensive unit that includes highly talented linebackers like Caleb Woodson and Jaden Keller, he’s excited to continue building on the defensive foundation already in place. With strong leadership and playmaking ability within the group, Siefkes sees an opportunity to elevate the linebacking corps even further. 

“The biggest thing I look for in linebackers is their ability to run and hit,” Siefkes stated. “[Woodson and Keller] are always around the ball, and that’s something you can’t really coach into them. They have that natural instinct and desire to always be near the football." 

Broadening from linebackers, Siefkes’ defensive philosophy extends to the entire unit, with a focus on simplicity and adaptability. The coach believes in creating a system that’s straightforward to teach, yet complex enough to challenge opponents. Having coached every position on the defense, from the defensive line to the secondary, Siefkes is confident in his ability to tailor the system to the strengths of his players. 

“I’ve coached every position on defense,” he said. “That flexibility helps when running a system where players need to take on multiple roles. It allows me to adjust and maximize their potential.” 

With the new defensive scheme in motion, Siefkes is now turning his attention to the immediate task at hand: preparing the team for spring practices. Winter workouts have begun, and this phase of preparation is crucial for laying the physical foundation for the challenges ahead. 

“This time of year is all about building endurance, muscle mass and physical strength—creating the ‘armor’ our players need,” Siefkes explained. 

Looking ahead, the new defensive coordinator knows the importance of cultivating both physical and mental toughness. “Winter workouts set the tone for spring ball,” Siefkes stated. “It’s about creating hunger, a drive for competition. We want our guys physically and mentally ready to hit the ground running when spring practices begin.” 

With his focus on developing versatile, well-rounded athletes, Siefkes is confident that Virginia Tech’s defense is ready to rise to the challenge. As the RenewALL deadline approaches, now is the perfect time to secure your 2025 season tickets and experience Siefkes’ inaugural season at the helm of the Tech’s defense.
