Master scouting report
Prongos is a developmental tackle whose movement remains the best reason to invest in the work still ahead. The appeal is a blocker who can arrive balanced and adjust; the concern is whether that useful position survives force through contact. His late entry into football gives the progression context, while the starting experience makes the next standard more demanding than potential alone.
01Late start, substantial recent work
Stanford records 12 starts at left tackle for Prongos in 2025. At UCLA, he appeared in ten games across three seasons, including nine appearances and eight starts in 2024. That 2024 season included starts at right tackle and right guard before his Stanford year on the left side. He began playing football as a high-school senior. He has progressed from a late introduction to football into regular responsibility at major college programs. His next step is making the technique as dependable as his place in the lineup.
02A base that moves with him
Prongos's movement is most attractive when his base stays underneath him, allowing the body to travel as an organized unit. That quality matters because a tackle must do more than arrive at the rusher's path; he needs a usable position from which to respond to the next movement. For Prongos, balanced movement is the foundation of the tackle case, giving the defense more than one obstacle to solve before reaching the quarterback. The best developmental use is to preserve that mobility while improving the contact that follows, so adding strength or seeking a bigger initial strike does not come at the expense of control.
03Position has to survive contact
Quick hands and recovery balance help him stay in the contest, but high pads can expose his chest to the rusher. That creates a clear coaching priority: keep the position strong enough that the first contact does not surrender the advantage created by his feet. Brandon Thorn questions the anchor and predictability of his protection despite useful movement. The improvement is to make leverage and hand placement more consistent, allowing the block to continue instead of requiring another recovery. His movement gives him a route into the contest; holding the relationship through force is what makes that route reliable.
04An experienced player still building
In Stanford's April spring report, Prongos said he returned because he still had work to do before pursuing the NFL. He also described a goal of raising the offensive line's standard and using that group to lift the team. The returning starter is accepting responsibility for both his own execution and the quality of the group around him. The useful expectation is repeatable blocking: fewer breakdowns and more control through contact. For a tackle, that standard has a practical test: reach a useful position, hold it through contact and finish the assignment.
05What the run game needs
The same profile identifies continued work on run-blocking leverage and hand placement, making sustained contact a priority beyond pass protection. A movement-oriented run plan offers a plausible way to use his balance while that part of the game develops. His experience at guard provides additional college context, but the full Stanford season at left tackle is the clearest recent sample for judging an NFL assignment. The line needs that execution across the calls a game demands, including the snaps that put his less developed skills under pressure. That is the practical meaning of the higher standard he described in spring.
Strengths
Body control and a stable moving base give the tackle projection a specific technical foundation.
Twenty starts across his last two college seasons provide meaningful responsibility alongside the late-start background.
Concerns
High pads and inconsistent hand placement can undermine the useful position created by his movement.
His anchor remains a protection concern.
NFL role and scheme fit
Keep the primary assessment at tackle, where his movement and balance offer a reason to develop him. A plan that uses movement while demanding better leverage through contact is a sensible starting point. The earlier guard work adds background, while his recent left-tackle responsibility provides the clearest starting point. He should earn broader responsibility by making the quality of his blocks repeatable across the calls the offense needs.
Bottom line
Prongos has a real technical asset in the way he moves while staying organized. Making that position hold up through contact would give the projection a much firmer basis. The late football start explains part of the development story, but his recent starting record makes consistent execution the next useful measure. Sustaining that progress would let the offense trust him with a broader assignment.
