Summary

Spencer Brown was drafted in the 2021 NFL Draft, Round 3, (pick 93). Brown entered the NFL as a rare physical specimen: a 6′8″ tackle with impressive athleticism, smooth feet, and long arms. Coming out of a smaller college program (Northern Iowa), he showed strong upside in pass protection and movement across the line.

With the Buffalo Bills, Brown has developed into a full-time starter at right tackle and earned a four-year contract extension in 2024, signalling the team’s commitment despite some development needed. Buffalo Rumblings

His career so far reflects a high-floor prospect who has matured into his role; his strengths lean toward pass protection and movement, while his development has centered on consistency and run-blocking finesse.

Strengths

• Elite length, size, and athleticism for the position: At 6′8″ with long arms and good footwork, Brown’s physical tools immediately stand out.

• Pass protection ability & movement: Scouts praised his ability to slide, get set quickly after the snap, and mirror edge rushers more easily than many at his size. NFL Draft Buzz

• Sustain-and-finish mentality: He shows willingness to sustain blocks, uses his hands effectively, and can drive defenders in the run game when in position.

• Durability and growth: Starting many games and earning a contract extension shows that he’s earned trust and is progressing in the role. Reuters

Weaknesses

• Run-blocking and anchor in power schemes: Because of his height and leverage issues, some evaluations noted that he needs to prove his worth consistently in straight-ahead power run games. NFL Draft Buzz

• Leverage, base, and pad level concerns: Some scouts flagged that at his height, when Brown doesn’t bend his knees or get low, defenders can get underneath him; dealing with quickness and power in tight spaces has been an issue. thedraftscout.com

• Upside vs elite tackles still uncertain: While his physical tools are excellent, his ceiling in elite run-scheme and against top-tier pass rushers is still under evaluation. Some inconsistency remains. Buffalo Rumblings

Fit & Outlook

Spencer Brown projects as a strong starting right tackle with a high floor and meaningful room for growth. His floor is firm: he has the physical tools, already trusted by the Bills, and is capable in pass protection. The ceiling, if fully realized, is as a dominant right tackle who handles both pass and run well.

The key to his further rise will be:

• Improving his pad level and leverage to handle power rushers and run-blocks consistently.

• Becoming more dominant in the run game (drive blocks, second-level blocks).

• Maintaining and improving his technique and consistency week to week against top defenders.
