Master scouting report

Siereveld is a guard prospect with meaningful tackle experience, strong contact skills and a clearer route to success when the space around him is controlled. His hands and balance can sustain a block through contact. The question is whether his feet and decisions keep up when the defense changes the collision's location.

01Tackle experience, guard assessment

Ohio State credits Siereveld with 14 starts in 2025 and seven starts across 16 appearances in 2024. He served as a captain and earned second-team All-Big Ten recognition in 2025. Mike Renner favors guard after Siereveld's 2025 left-tackle season. The two seasons give him 21 starts and experience preparing for a demanding weekly assignment. At guard, shorter adjustments would put his contact skills closer to the play. The primary assessment is guard, with tackle flexibility.

02Control begins with the hands

His most convincing blocks combine purposeful hand placement with the ability to maintain a balanced position through contact. Accurate hands and controlled aggression can keep an opponent occupied while Siereveld remains balanced enough to sustain the engagement. Matthew Jones also identifies useful grip and anchor, but cautions that the feet can stop after engagement. That difference matters: securing the defender initially is only half the job if the next movement leaves the block behind. The aim is sustained control, with the body following the hands rather than a spectacular first strike followed by an escape.

03Power and space ask different questions

Siereveld's stable base gives him a way to handle a rusher attacking directly through him. Jones questions his lateral range and balance against sudden movement outside. Harbaugh is more favorable about the footwork and ability to adjust; the shared lesson is that balance must remain available after the first response. Chris Farbolin's concern about speed reinforces the reason to examine an interior role, where Siereveld would defend a shorter path to the quarterback. That changes the problem rather than eliminating it: a quick interior defender can still punish a late step or an exposed side.

04Keep the block moving

There is useful force in Siereveld's run blocking, and a defender who lets him establish contact can have difficulty escaping the engagement. An offense can build on that by asking him to create and sustain space near the line, where his physicality has an immediate purpose. The finishing detail is to keep moving his feet with the target instead of letting his hands become the only connection. His aggression is an asset when it stays organized, because continued pressure can preserve the runner's path after the initial crease appears. A fit should reward controlled displacement and balance, without making repeated difficult recoveries in space the foundation of his workload.

05A quicker picture inside

Farbolin identifies stunts and assignment consistency as areas still needing work. Moving to guard brings neighboring blockers closer, but it also requires fast decisions when defenders exchange paths across that shared space. The priority is to recognize the change and arrive ready to engage, rather than rely on strength after the defender already owns the angle. His prior guard and tackle work is valuable preparation for that responsibility, although experience itself does not prove that every exchange is settled. His experience should make the next standard more demanding: identify the changing assignment, reach it on time and keep the block working.

The case for the player

Strengths

  • Hand control and a balanced, forceful approach give him a workable foundation for sustained contact.

  • Two seasons of substantial participation, including 21 starts, provide a stronger experience base than a single breakout stretch.

The questions that remain

Concerns

  • Lateral range and feet that stop after contact can allow a quick opponent to escape an initially favorable block.

  • Speed and changing assignments remain tests even if a guard role reduces the space he must defend.

Building the fit

NFL role and scheme fit

Use him first as an interior competitor in a balanced offense that values controlled physicality and stable protection. An outside assignment should be earned against speed; his tackle background offers an option. Treat the positional history as useful roster flexibility, with the actual lineup decision dependent on how well his technique holds up in the role.

The Draftanomics view

Bottom line

Siereveld has tangible blocking skills to build around, particularly when his hands, base and temperament work together. The clearest improvement would be consistency when the defense forces a second decision. Guard offers the more persuasive fit, provided he keeps his feet involved and makes the shorter, faster interior exchanges on time.
