The on-field drills for offensive linemen at the 2026 NFL Combine are officially underway in Indianapolis, and for the hometown Colts, the evaluation process has shifted into high gear. While the interview sessions and medical checks are critical, the measurable athletic testing on the Lucas Oil Stadium turf provides a crucial, standardized data point for every front office. For a Colts team that has long prioritized building through the trenches, identifying the next wave of talent to protect their franchise quarterback and establish the run is a perennial draft-season mission.
According to Colts Wire analysis, the team's focus during these combine workouts is honing in on several top prospects who fit their specific offensive scheme and could be realistic targets across various rounds of the upcoming draft. The report highlights three particular linemen who stand out as potential fits for the Horseshoe. Let's break down why these players warrant extra attention from Colts fans and analysts over the coming days.
The Athletic Mauler: OT Jordan Ellis, Alabama
The prototype for a modern NFL tackle often involves a rare blend of size, length, and foot quickness. Alabama's Jordan Ellis appears to check all those boxes, and his performance in Indianapolis will be scrutinized by a Colts team that could be looking for a long-term answer on the edges of their line. Ellis played in a pro-style system under Nick Saban, facing elite SEC competition weekly, which gives scouts a strong baseline for his technical proficiency and toughness.
For the Colts, Ellis represents the potential for a high-ceiling, Day 1 starter. General Manager Chris Ballard has consistently valued players from powerhouse programs who are "ready to go," and Ellis's pedigree suggests he could be. The key at the combine will be his athletic testing. If he posts elite numbers in the 40-yard dash (particularly the 10-yard split, which indicates explosiveness off the line) and the short shuttle (showing lateral agility in pass protection), he will solidify his status as a first-round talent. The Colts, depending on their draft position, could see him as the cornerstone left tackle of the future, a player who can handle the league's premier pass rushers one-on-one and open lanes in the team's outside zone running scheme.
The Versatile Interior Force: IOL Marcus Chen, Michigan
While tackle often grabs the headlines, the interior of the offensive line is where games are frequently won and lost. The Colts have enjoyed stability inside with players like Quenton Nelson, but planning for the future is essential. Michigan's Marcus Chen is a player who fits the Colts' mold perfectly. Chen played both guard and center at a high level for the Wolverines, showcasing the intelligence, strength, and wrestling background that the Colts' scouting department traditionally loves.
Chen's combine will be less about eye-popping 40 times and more about demonstrating functional strength and agility for the confined spaces of interior line play. His performance in the bench press will be noted, but more importantly, scouts will watch his footwork during positional drills. Can he mirror quickly in pass protection? Does he fire out with low pad level and power in run-blocking drills? His interviews will also carry significant weight; the ability to make line calls and process complex defensive fronts is paramount for an interior lineman in Shane Steichen's offense. Chen could be a target in the second or third round who offers immediate depth and the flexibility to play multiple spots, eventually growing into a long-term starter.
The Developmental Tackle with Upside: OT Liam O'Connell, Oregon
Not every draft pick is intended to start immediately. Finding and developing raw talent is a hallmark of successful franchises, and Oregon's Liam O'Connell is cited as a prospect who fits that developmental profile for Indianapolis. Possessing ideal tackle size and length, O'Connell's college tape shows flashes of dominance but also inconsistencies in technique. He is the classic "traits" prospect who could become a steal if coached up properly.
The combine is O'Connell's chance to turn potential into tangible, elite numbers. His measurements (arm length, hand size) will be critical. Then, his testing in drills like the three-cone drill and the broad jump will indicate his lower-body explosiveness and bend--key attributes for handling speed-to-power rushers. For the Colts, a strong combine from O'Connell could make him an attractive mid-round project. He could learn behind established veterans for a year or two while adding functional strength and refining his pass sets. In an era where capable offensive tackles are at a premium, using a Day 3 pick on a player with O'Connell's physical gifts is a calculated risk with a potentially massive payoff.
Why the Combine Matters for the Colts' Evaluation
For Chris Ballard and his staff, the combine is a vital piece of the puzzle, but not the entire picture. It confirms -- or raises questions about -- the athleticism they see on tape. The Colts' offensive scheme, which emphasizes outside zone runs and play-action passing, requires linemen who can move. They don't need statuesque maulers; they need agile, intelligent athletes who can reach block, pull, and get to the second level. The drills in Indianapolis are specifically designed to test that kind of movement.
Furthermore, the medical evaluations and formal interviews conducted this week are arguably just as important as the 40-yard dash time. A clean bill of health is non-negotiable for a high draft investment. The character and football IQ gleaned from face-to-face meetings can be the tiebreaker between two similarly graded players. The three prospects highlighted -- Ellis, Chen, and O'Connell -- will each go through this rigorous process with the Colts and 31 other teams watching closely.
As the offensive linemen run, jump, and drill in the building the Colts call home, the team's decision-makers will be building their final draft board. A standout performance from any of these three could cement their status as a target for Indianapolis come April. The work in Indy this week lays the foundation for the selections that will shape the roster for years to come. For a franchise built on the principle of controlling the line of scrimmage, there are few more important evaluations all year.
