former Notre Dame captain NFL, Sam Mustipher career, undrafted free agent success story, Jacksonville Jaguars offensive line

In a league that constantly turns over its rosters and favors youth, Sam Mustipher continues to find a way.

The former Notre Dame captain and undrafted free agent received another opportunity this week when the Jacksonville Jaguars signed him to their roster. The move came shortly after the team placed center Trystan Colon on the reserve/retired list, creating an opening on the offensive line. For Mustipher, it represents one more chance to keep an improbable NFL career alive heading into the 2026 season.

At an age when many players are forced out of the league, Mustipher is still competing. His path from overlooked college prospect to reliable professional has become one of the quieter success stories in recent NFL history.

From Notre Dame Leadership to the NFL Dream

Sam Mustipher arrived at Notre Dame as a developmental prospect and left as a team captain. He redshirted in 2014 and gradually worked his way into the rotation before becoming a full-time starter. By the end of his college career he had started 38 of 47 games for the Fighting Irish.

His senior season in 2017 stood out. Mustipher started all 13 games at center and helped anchor an offensive line that supported a strong ground game. The unit paved the way for more than 3,500 rushing yards and 35 rushing touchdowns that year. Just as importantly, Mustipher did not allow a sack or quarterback hit during the entire season, a testament to his technique and reliability in pass protection.

In 2018 he was named a captain and once again started every game. Leadership, consistency, and toughness defined his time in South Bend. Those same traits would later become the foundation of his professional career.

Despite the production and the captaincy, Mustipher went unselected in the 2019 NFL Draft. Like many interior offensive linemen, he lacked the elite athletic testing numbers that often catch the attention of scouts. What he possessed instead was experience, football intelligence, and a competitive edge that does not always show up in measurable workouts.

Beating the Odds as an Undrafted Free Agent

The Chicago Bears signed Mustipher as an undrafted free agent after the draft. Making an NFL roster is difficult enough for drafted players. For undrafted free agents, the margin for error is almost nonexistent. Most never make it past training camp.

Mustipher not only made the roster — he eventually became a starter. Over his first several seasons with the Bears he appeared in dozens of games and started 40 of his first 43 professional contests at center. In a league that often discards players quickly, he carved out a genuine role through reliability and preparation.

His ability to process information, make line calls, and hold up against NFL defensive tackles kept him employed. Centers who can consistently execute the mental side of the position often outlast more athletic but less polished players. Mustipher proved to be one of those steady, dependable options.

A Journeyman Path Across the League

After his time in Chicago, Mustipher’s career took him to several other organizations. He spent time with the Baltimore Ravens, Los Angeles Chargers, and Denver Broncos. Each stop required him to learn new systems, earn the trust of new coaches, and compete against younger players fighting for the same roster spots.

Last season he appeared in one regular-season game and two playoff contests for the Broncos while serving as a backup. Even in a limited role, he remained on an active NFL roster late into the year and into the postseason. That kind of longevity is rare for a player who entered the league without the security of being drafted.

Through it all, Mustipher has appeared in 65 career NFL games with 43 starts. Those numbers reflect more than just survival. They reflect a player who continually found ways to contribute and who organizations continued to value when depth was needed.

Why the Jaguars Made the Call

Jacksonville’s decision to sign Mustipher was practical. When Trystan Colon unexpectedly retired, the Jaguars needed experienced depth at center. Mustipher offered exactly that a veteran who has started significant snaps in the NFL and understands the demands of the position.

The Jaguars already have former Notre Dame offensive lineman Robert Hainsey on the roster, creating a small but meaningful connection for Mustipher. Familiarity with another former Domer can ease the transition into a new building, even if only slightly.

For Jacksonville, the signing carries low risk and potential reward. Veteran centers who can step in during camp, provide quality repetitions in practice, and be ready if injuries occur are valuable commodities. Mustipher fits that profile.

The Broader Reality of NFL Longevity

Mustipher’s career highlights a larger truth about the National Football League. While the league celebrates first-round picks and athletic freaks, it also has room for players who maximize their opportunities through preparation and toughness. Undrafted free agents who last multiple seasons often share similar traits: high football IQ, dependability, and an ability to earn the trust of coaches and teammates.

Reaching a seventh season is an accomplishment for any player. Doing so after going undrafted and bouncing between multiple teams makes the achievement more impressive. Mustipher has already outlasted many players who were selected ahead of him in 2019.

The physical toll of playing offensive line in the NFL is significant. The mental demands are equally high. Centers must identify defensive fronts, communicate protections, and adjust in real time. Mustipher’s ability to handle those responsibilities has kept him relevant even as younger players enter the league every year.

What Comes Next for Sam Mustipher

The Jaguars give Mustipher a fresh opportunity to compete for a roster spot or a meaningful depth role. Training camp and the preseason will determine how much he contributes in 2026. Regardless of the final outcome, the signing itself represents another chapter in a career built on persistence.

For former Notre Dame fans, Mustipher’s continued presence in the NFL serves as a reminder of the program’s ability to develop tough, reliable offensive linemen. For neutral observers, his story offers a quieter counterpoint to the flashier narratives that dominate sports coverage.

Success in the NFL is often measured by draft position, Pro Bowl selections, and contracts. Mustipher’s career suggests another measuring stick: the ability to keep finding a way onto a roster year after year when many expected him to be long gone.

A Career Defined by Resilience

Sam Mustipher was never supposed to last this long. He was not a high draft pick. He did not arrive in the league with overwhelming athletic traits. What he brought instead was preparation, toughness, and a refusal to accept the long odds that face most undrafted players.

From his days as a captain at Notre Dame to his years starting in Chicago and his subsequent stops around the league, Mustipher has consistently maximized every opportunity. The Jacksonville Jaguars have now given him one more.

Whether this chapter becomes a significant one or simply another stop along the way, it fits the larger pattern of his career. Sam Mustipher keeps showing up, keeps competing, and keeps proving that an unlikely NFL journey can still find new life.
