During the NFL offseason, players focus on developing chemistry and bonding, particularly among skill position teammates like wide receivers and running backs. Dallas Cowboys quarterback Dak Prescott took his offensive skill players to various locations including San Diego, Lake Oconey in Georgia, and Lake Oswego in Oregon. However, the offensive line’s cohesion is just as crucial, and the Cowboys benefit from having elite offensive line coach Duke Manyweather based in Frisco, Texas, which allows the unit to train locally.
Tyler Guyton, the Cowboys’ left tackle, highlighted Manyweather’s specialized expertise in offensive line training, which emphasizes foundational strength, stance, and technique, creating an environment where players competing for the same position can push each other to improve. Manyweather, a former Division II college player from Humboldt State in California, realized early he would excel as a coach rather than an NFL player. His training philosophy centers on the mind, body, and craft, aiming to perfect technique and physical readiness.
Manyweather’s first notable client was Philadelphia Eagles’ Pro Bowl right tackle Lane Johnson, with whom he organized a two-day offensive line summit to combat elite pass rushers like Von Miller. This led to an annual offensive line gathering in Frisco starting in 2018, attracting top linemen from various NFL teams, including the Chiefs’ Mitchell Schwartz and Saints’ Terron Armstead. Manyweather continues to train NFL offensive linemen year-round, with increased offseason activity when players are away from their teams, providing a valuable resource for elite players striving to compete at the highest level.
Cowboys left guard Tyler Smith praised the training environment, noting the benefit of working alongside top peers such as Rashawn Slater and Terron Armstead. Both Slater and Chiefs’ Trae Smith, entering the final season of their rookie contracts, chose to spend their spring training with Manyweather before mandatory mini-camps.
Manyweather’s influence in the Cowboys organization grew over the years as he trained veterans like Jermee Parnell and Ronald Leary. When Zack Martin, a first-team All-Pro right guard, became a client, Manyweather firmly established himself as the go-to trainer for Dallas’ offensive line. His work helps maximize the unit’s potential, earning respect from players and coaches alike as a stabilizing force.
New Cowboys offensive line coach Connor Riley and assistant Ramón Chinn Sr. met with Manyweather to coordinate player development during coaching downtime, ensuring alignment on training goals. Manyweather’s role is to enhance players’ progression efficiently without altering their core techniques.
As training camp approaches, the Cowboys’ starting offensive linemen engage in two-hour sessions with Manyweather, Monday through Friday. Tyler Guyton, the 2024 first-round pick, has focused on improving his stance, balance, and strength to reduce penalties and improve performance at left tackle. Tyler Smith, another key lineman, sharpens his first three steps to optimize leverage and power in both run and pass blocking.
Center Cooper Beebe, who transitioned from guard and had a challenging rookie season, benefits from Manyweather’s collaboration with coach Riley to adjust and enhance his skills. First-round pick Tyler Booker, trained by Manyweather since his Alabama days, prepares to switch from left guard to right guard, with cross-training to develop versatility and avoid injury from asymmetrical muscle use.
Right tackle Terence Steele, recovering from serious knee injuries, works closely with Manyweather to regain mobility, refine technique, and improve hand use, aiming to reduce quarterback pressures while maintaining strong run blocking.
Fan Take: This offseason glimpse into the Dallas Cowboys’ offensive line training reveals how crucial specialized coaching and player collaboration are for building a dominant unit. For NFL fans, the emphasis on technique, versatility, and injury prevention signals a shift toward smarter, more sustainable player development that could redefine how the game is played and protected at the line of scrimmage.
