The Jacksonville Jaguars made a pair of quiet, deliberate additions on Thursday, signing cornerback Dane Jackson and offensive lineman Trystan Colon to the roster. Neither move will force a redrafting of depth charts or steal headlines from the team's more established names. That is exactly the point.
Jackson, a veteran of five NFL seasons, arrives from a stop with the Carolina Panthers preceded by four years in Buffalo. Colon, meanwhile, brings a versatile interior presence from recent tenures with the Arizona Cardinals and New York Jets. Both signings are depth moves in the truest sense of the term, but in a league where a season can turn on the seventh defensive back or the second-string center being ready when called, these are the kinds of transactions that matter most in June.
For the Jaguars, who are navigating a restructured roster under first-year head coach Liam Coen and general manager James Gladstone, the additions serve a specific purpose. This is a team that has spent the spring reshaping its identity on both sides of the ball, and the front office is clearly prioritizing experience in the margins.
Jackson, 27, has started 27 games across his career, most of them for a Bills defense that consistently ranked among the league's best. He knows how to play in a system that demands discipline on the back end. He understands what it looks like when a secondary communicates before the snap. That knowledge, for a young Jaguars cornerback room that includes last year's fourth-round pick Jarrian Jones, developmental prospect Montaric Brown, and 2026 rookie Caleb Ransaw, is invaluable.
Jackson is not going to walk into the building and push for a starting job. The Jaguars have Jourdan Lewis, a veteran slot corner who has played winning football for years, and a group of young players competing for snaps on the perimeter. But in an AFC South that now features C.J. Stroud throwing to Stefon Diggs and Nico Collins, with Anthony Richardson's arm and legs in Indianapolis, defensive back depth is not a luxury. It is a necessity.
What Jackson offers is a baseline of competency that can withstand a bad matchup. He knows how to play outside leverage. He can press at the line without panicking when beaten. He has been in playoff games and knows the difference between a regular-season Tuesday and a January Saturday. Those are not things you can teach in training camp.
Colon, meanwhile, slides into an interior offensive line room that has been rebuilt with deliberate intent. The Jaguars signed Patrick Mekari this offseason and drafted Oregon guard Emmanuel Pregnon in the third round. They have Ezra Cleveland and Robert Hainsey as established pieces. Colon adds a sixth or seventh option who can play either guard or center, which is the kind of flexibility that offensive line coaches dream about in August.
The Jaguars' offensive line was a quiet strength in 2025, anchored by left tackle Walker Little and right tackle Anton Harrison. Trevor Lawrence threw for over 4,000 yards last season and was sacked less frequently than in previous years. The interior, when healthy, was solid. But the Jaguars have not historically been a deep team along the offensive front. One injury to a starter has, in past seasons, sent a ripple through the entire offense. Colon is the kind of player who absorbs that ripple before it becomes a wave.
He has started ten games over the last two seasons, most of them at center. He understands the communication required to set protections. He is not a star. He does not need to be. The Jaguars are paying him to be the thirteenth or fourteenth man on a 53-man roster who, if all goes well, never sees the field in a meaningful snap. But if he does, the offense should not collapse.
Both signings come ahead of mandatory minicamp, which is just days away. The Jaguars will gather for their final organized team activities before the summer break, and both Jackson and Colon will be there, learning the playbook, building chemistry, and proving to the coaching staff that they can be trusted.
For a team with Super Bowl futures listed at +2500 on FanDuel, these moves are not going to move the betting line. They are not going to sell jerseys. But they are the kind of moves that good organizations make in the quiet months between the draft and training camp. The Jaguars, under Coen and Gladstone, are trying to become a good organization.
Jackson's journey has been instructive. He was a seventh-round pick out of Pitt in 2020, a draft that happened during the pandemic and forced every rookie to learn without the benefit of a normal offseason. He fought his way onto the Bills roster, started games in a Super Bowl contender's secondary, and then found himself in Carolina last season, playing for a team that won only five games. He knows what a winning culture looks like because he has been in one. He knows what a losing culture looks like because he has been in that, too.
The Jaguars believe they are building something in between, something that can sustain over time. They have the quarterback in Trevor Lawrence, who threw 29 touchdown passes and ran for nine more last season. They have the weapons, with Brian Thomas Jr. emerging as a downfield threat and Jakobi Meyers providing the reliable chain-moving presence that every offense needs. They have Travis Hunter, the two-way player whose unique skill set makes him a constant topic of conversation. But the foundation of any team that wins consistently is the second and third layers of the roster.
That is where Jackson and Colon fit.
Colon, a former undrafted free agent from Missouri, has carved out a career by being reliable. He has played for three teams in five seasons but has stuck in the league because he can line up at center or guard and not make mistakes. He is the kind of player who knows every protection call, who understands what the quarterback sees, and who can make the line calls if the center goes down. That knowledge does not show up in a stat sheet, but it shows up in December when a backup is suddenly thrust into a playoff chase.
Signing players like Colon and Jackson is not glamorous. But it is how teams avoid the kind of collapse that defined the Jaguars in the years before Lawrence arrived. It is how a franchise stops being a team that makes excuses and becomes a team that wins games it is supposed to win.
The Jaguars are not done adding players. They have cap space, roughly $9.56 million per Over The Cap, though a significant portion of that is tied up in dead money from previous years' mismanagement. They will likely continue to comb the veteran market for bargains. But for now, they have two new players who understand what it means to be a professional.
That matters more in June than most fans realize.
