Spencer Fano's 32-Inch Arms: NFL Draft's Biggest Measurement Question

Spencer Fano's 32-Inch Arms: NFL Draft's Biggest Measurement Question

Spencer Fano's arm length measurement at the 2026 NFL Combine has become the defining question mark for one of this year's most intriguing offensive line prospects. The Utah tackle measured 32 1/8 inches in arm length, falling below the typical 33-inch standard NFL teams seek for starting tackles.

At 6-foot-5 1/2 and 311 pounds, Fano brings impressive athleticism to the table. His 4.91-second 40-yard dash tied for second-fastest among offensive linemen, while his 1.72-second 10-yard split ranked third among all blockers. The numbers suggest a player with the foot speed to handle NFL edge rushers, but the arm length deficiency creates a fundamental concern.

Fano's college production shows steady improvement that might ease some concerns. As a true freshman in 2023, he allowed 2 sacks and 21 combined sacks + hits + pressures in 12 games. The following year at right tackle, those numbers improved to 1 sack and 14 combined pressures. Most impressively, Fano went through the entire 2025 regular season allowing zero sacks and just 5 combined pressures.

The comparison to Will Campbell provides relevant context. The Patriots' 2025 first-round pick measured 32 5/8-inch arms and still allowed 14 pressures in Super Bowl LIX. Campbell's success despite similar arm length concerns suggests Fano's elite athleticism might compensate for the measurement deficiency.

History shows this isn't unprecedented. Alijah Vera-Tucker measured 32 1/8-inch arms at the 2021 combine and was moved to guard by the Jets. Peter Skoronski measured 32 1/4-inch arms in 2023 and slipped out of the top 10 despite being widely projected as a top-five pick before the measurement.

Fano's versatility adds another layer to the evaluation. He started at left tackle in 2023 before moving to right tackle for his final two seasons at Utah. This experience on both sides could make a transition to guard less jarring if NFL teams determine that's his best position.

The timing of this measurement debate is particularly interesting. Fano's pro day and private workouts will be heavily scrutinized as teams try to determine whether his arm length is a fatal flaw or merely a challenge to overcome. With the 2026 NFL Draft set for April 23-25 in Green Bay, Fano has limited time to convince teams his arm length won't limit him to guard at the professional level.

Why Arm Length Matters for NFL Tackles

NFL teams prioritize arm length because longer arms allow tackles to keep pass rushers at a distance, engage blocks more effectively, and control the line of scrimmage. The 33-inch benchmark isn't arbitrary—it represents the minimum length most teams believe necessary to compete against elite edge rushers who can generate power from leverage.

What to Watch: Fano's Path Forward

Teams will be watching Fano's upcoming pro day workouts closely, particularly his pass sets and hand placement drills. His 32-inch vertical jump and 9-foot-3 broad jump already demonstrate explosive lower-body power that could help compensate for shorter arms. The question isn't whether Fano can play in the NFL—it's whether he can excel as a tackle or if his physical dimensions will push him inside to guard.
