Standing at 6'7" from an early age, Koziol’s towering frame was immediately noticeable, and it became a focal point of his athletic development.

His parents encouraged a balanced approach to sports, allowing him to explore multiple disciplines before focusing on football.

NFL Draft

Tanner Koziol’s journey to the NFL culminated in the 2026 NFL Draft, where he was selected by the Jacksonville Jaguars in the fifth round with the 164th overall pick. The selection marked a significant achievement for Koziol, who had spent years proving himself as a developmental prospect with the potential to contribute at the professional level.

The Jaguars, under the leadership of general manager Trent Baalke and head coach Doug Pederson, prioritized the tight end position in the draft, seeking to add versatile weapons to their offensive scheme. Koziol’s rare combination of size, athleticism, and blocking ability made him an ideal fit for Pederson’s system, which emphasizes a balanced offensive attack and the use of multiple personnel groupings. His draft position reflected the belief that his physical tools and potential could translate to the NFL, even if he required additional seasoning.

Koziol’s draft profile highlighted his strengths as a blocker, with analysts noting his willingness to engage with defenders in the run game and his ability to seal the edge on outside zone plays. His size and body control also made him a matchup problem in the passing game, particularly in red-zone situations where his length could be utilized to high-point the ball over smaller defenders. Scouts also pointed to his character and work ethic as positives, traits that were evident during his pre-draft interviews and medical evaluations.

The Jaguars’ decision to draft Koziol in the fifth round was seen as a strategic move to develop a long-term option at tight end, with an eye toward grooming him for a more prominent role in the future. His rookie season would likely involve a period of acclimation to the speed and physicality of the NFL, with expectations that he would contribute primarily as a blocking tight end while developing his receiving skills. The Jaguars’ depth chart at tight end, which included veterans such as Evan Engram and Luke Farrell, provided Koziol with a supportive environment to learn and grow.

Professional Career

As of the time of this writing, Tanner Koziol’s NFL career is in its infancy, with no regular-season games played. His professional career officially began when he signed his rookie contract with the Jacksonville Jaguars following the 2026 NFL Draft. The terms of the deal were not publicly disclosed, but as a fifth-round selection, Koziol’s contract would include a base salary in the range of $1.1 million to $1.3 million for his rookie season, along with signing bonuses and performance incentives.

Koziol joined the Jaguars during a critical phase in the franchise’s development, as the team sought to build on its 2025 season, which saw them finish with a 10-7 record and a playoff berth. The Jaguars’ offense, under the guidance of offensive coordinator Press Taylor, operates with a blend of run and pass concepts, often utilizing tight ends in both traditional and hybrid roles. Koziol’s ability to contribute in the run game as a lead blocker and in the passing game as a safety valve has positioned him as a developmental option with upside.

The Jaguars have emphasized the importance of player development, particularly with younger tight ends, and Koziol has been assigned to work closely with the coaching staff to refine his technique and football IQ. His rookie year is likely to focus on special teams contributions, with an eye toward earning playing time on offense in situational packages. The Jaguars’ depth at tight end, combined with the experience of veterans like Engram and Farrell, provides Koziol with a valuable learning opportunity.

During training camp and the preseason, Koziol has been expected to demonstrate his readiness to contribute in a limited role. His ability to block effectively in the run game has been a focal point for coaches, as the Jaguars seek to improve their offensive line play and create more rushing opportunities. In the passing game, Koziol’s size and athleticism could make him a red-zone target, particularly in play-action concepts where his ability to win contested catches would be advantageous.

Looking ahead to the 2026 season, Koziol’s ultimate success in the NFL will depend on his ability to adapt to the speed of the game and refine his route-running while maintaining his blocking efficiency. The Jaguars’ offensive scheme, which incorporates a variety of personnel groupings, may allow Koziol to carve out a niche early in his career. His long-term projection includes the potential to develop into a starting-caliber tight end, particularly if he continues to improve his receiving skills and football acumen.

Playing Style & Strengths

Tanner Koziol’s playing style is defined by his rare blend of size, athleticism, and technical proficiency, which makes him an intriguing prospect at the tight end position. Standing at 6'7" and weighing 240 pounds, Koziol possesses the physical dimensions of an elite mismatch weapon, particularly in the passing game. His long arms and wingspan create significant advantages in contested-catch situations, where his ability to high-point the ball over defenders has drawn comparisons to other successful tight ends in the league.

As a blocker, Koziol’s strength and technique stand out. He excels in the run game, where his ability to engage with defensive ends and linebackers allows him to drive them off the ball and create lanes for ball carriers. His footwork in pass protection is serviceable for a rookie, with coaches noting his willingness to set a firm edge and maintain his leverage. Koziol’s blocking profile fits well in an offense that emphasizes a physical, downhill rushing attack, where tight ends are often deployed as extra linemen in the formation.

In the passing game, Koziol’s route-running is still developing, but his size and athleticism make him a dangerous weapon on play-action and deep crossing routes. He has shown the ability to separate from linebackers in zone coverage, using his length to win contested throws. His hands are reliable, with few drops in his collegiate career, and his body control allows him to adjust to the ball in the air. Koziol’s red-zone acumen could become a significant asset for the Jaguars, particularly in situations where the defense is forced to cover him one-on-one.

One of Koziol’s most underrated strengths is his football IQ. He demonstrates a strong understanding of defensive coverages and has the ability to diagnose blitzes quickly. His pre-snap recognition allows him to adjust his blocking schemes or route stems based on the defensive alignment, a trait that is highly valued in the NFL. Additionally, Koziol’s work ethic and coachability have been praised by members of the Jaguars’ staff, who view him as a player who is committed to continuous improvement.

Compared to other tight ends in the league, Koziol’s profile is somewhat unique. He is not a traditional receiving tight end like Travis Kelce or Darren Waller, nor is he a pure in-line blocker like George Kittle. Instead, his skill set positions him as a hybrid tight end who can contribute in multiple facets of the game. His ability to line up inline, in the slot, or as an extra tackle in jumbo packages gives offensive coordinators flexibility in their play-calling.

To maximize his potential, Koziol will need to refine his consistency as a route-runner and improve his burst out of his breaks. His long stride makes him a threat on deep posts, but his ability to separate in short-to-intermediate routes will determine his offensive role in the coming years. If he can develop into a reliable red-zone target and a competent blocker in protection, Koziol has the tools to become a valuable contributor for the Jaguars.

Personal Life

Off the field, Tanner Koziol is known for maintaining a low public profile, a trait that is not uncommon among rookie players prioritizing their professional development. He grew up in a close-knit family, with his parents, Jim and Lisa Koziol, serving as his primary support system throughout his athletic career. Koziol has often credited his family for instilling the discipline and humility that have guided him through high school and into the NFL.

He is active on social media, though he uses his platforms primarily to share workout clips, training updates, and inspirational messages rather than personal details. Koziol’s Instagram and Twitter accounts feature a mix of football-related content and glimpses into his training regimen, highlighting his dedication to his craft. He has also been involved in community outreach programs, including youth football camps in the Chicago area, where he mentors young athletes and emphasizes the importance of education and character development.

Koziol’s interests outside of football include weightlifting, film study, and outdoor activities such as fishing and hiking. He has expressed a desire to one day pursue a degree in sports management, reflecting his long-term interest in the business side of athletics. His relationships with teammates have been described as positive, with veterans on the Jaguars’ roster praising his professionalism and willingness to learn.

Off-season training is a critical component of Koziol’s approach to the game. He works closely with the Jaguars’ strength and conditioning staff to maintain his physical attributes, focusing on explosive power, flexibility, and injury prevention. Koziol’s training routine often includes plyometrics, agility drills, and position-specific work to refine his blocking and receiving techniques. His commitment to his craft has earned him respect among coaches and teammates alike.

Legacy & Future Outlook

Tanner Koziol’s journey to the NFL is still in its early stages, but his trajectory suggests he has the potential to carve out a meaningful career as a tight end. His draft selection by the Jacksonville Jaguars reflects the belief that he can develop into a key contributor, particularly in a system that values blocking and versatility. Koziol’s legacy will ultimately be defined by his ability to fulfill the promise he showed as a high school prospect while adapting to the demands of professional football.

In the short term, Koziol’s success will hinge on his ability to earn playing time as a rookie. The Jaguars’ tight end group is experienced, which provides him with a safety net while he acclimates to the speed of the NFL. His role in 2026 is likely to be modest, with a focus on special teams and situational snaps. However, if he can demonstrate progress in his route-running and pass protection, he may see increased opportunities as the season progresses.

Looking further ahead, Koziol’s future outlook is tied to his development as a complete tight end. If he can refine his receiving skills while maintaining his blocking efficiency, he has the potential to become a starting-caliber player in the NFL. The tight end position has evolved to include hybrid roles, and Koziol’s size and athleticism make him a natural fit for modern offenses that emphasize versatility. His ability to contribute in the run game, pass protection, and red-zone situations could make him a valuable asset for years to come.

The Jaguars’ commitment to developing young talent suggests that Koziol will have the resources and support needed to reach his potential. His work ethic, football IQ, and physical tools provide a strong foundation, but his ultimate impact will depend on his ability to translate those attributes to consistent on-field production. If he can stay healthy and continue to improve, Tanner Koziol has the potential to become a key piece of the Jaguars’ offense and a respected figure in the NFL.

For now, Koziol remains a project with significant upside. His journey from Bloomingdale to the NFL is a testament to his dedication and the support of those around him. With continued growth and development, he has the opportunity to leave a lasting legacy as a loyal and effective tight end for the Jacksonville Jaguars.
