When evaluating modern running backs, raw production in college only tells part of the story. Scouts and analysts lean heavily on athletic testing data to project how college dominance translates to the professional level. Former Ohio State and Ole Miss running back Quinshon Judkins answered major questions about his top-end speed and explosiveness at the 2025 NFL Scouting Combine, cementing his status as an elite prospect with his official testing numbers.
At the combine, Quinshon Judkins clocked an official 4.48-second 40-yard dash. For a runner built with a thick, powerful frame at 5-foot-11 and 221 pounds, this time shattered any lingering pre-draft concerns regarding whether he possessed true breakaway speed or merely functioned as a volume-dependent interior grinder.
Breakdown of the 4.48-Second Forty
The 40-yard dash is rarely just about the final number on the stopwatch; it is a sequence of distinct phases that reveal an athlete's acceleration and speed maintenance.
The 10-Yard Split
Explosiveness out of a three-point stance dictates how quickly a back can cross the line of scrimmage before linebackers diagnose the gap. Judkins posted a blistering 1.51-second 10-yard split, placing him in the 90th percentile historical range for his position group. This rapid initial burst explains his success on inside zone and power runs, where getting up to top speed within two steps determines whether a play gains five yards or gets stuffed behind the line.
Speed Maintenance and Frame Proportion
Running 4.48 seconds at 221 pounds yields a strong body-mass-to-speed ratio. Many prospects who run in the mid-4.4s weigh under 205 pounds, sacrificing tackle-breaking mass for straight-line velocity. Judkins combined heavy-back durability with sub-4.5 speed, proving he doesn't have to choose between punishing defenders and pulling away from secondary angles in the open field.
Contextualizing the Explosive Metrics
Speed metrics gain true meaning when paired with lower-body explosion numbers captured during vertical and horizontal jumping drills. Judkins didn't just run well; he dominated the field events in Indianapolis.
- Vertical Jump: He recorded a 38.5-inch vertical, demonstrating exceptional lower-body power transfer.
- Broad Jump: He leaped 11 feet, 0 inches (132 inches), which ranked among the highest marks for running backs historically.
- Contact Balance Correlation: Explosive jumping numbers heavily correlate with tackle-breaking ability. A powerful lower half enables a runner to absorb direct hits from linebackers while maintaining forward momentum.
These testing results backed up the violent running style scouts saw on film at both Ole Miss and Ohio State. Rather than seeking open space exclusively by bouncing runs outside, Judkins regularly embraced contact, using his burst to dictate the angle of collision.
How Speed Translates to Scheme Fit
Understanding athletic metrics allows offensive coordinators to design schemes that maximize a player's physical traits. With his verified acceleration, Judkins fits specific blocking schemes exceptionally well.
Zone Schemes
Because of his 1.51-second split, Judkins excels in outside and inside zone concepts. He demonstrates the quick decision-making required to press the offensive line, read the leverage of the unblocked defender, and plant his foot to cut upfield.
Gap and Power Schemes
While he possesses the speed to bounce runs to the perimeter, his size allows him to function as a primary between-the-tackles option. Teams looking for a workhorse back benefit from a player who hits the hole decisively without needing a long runway to build momentum.
Common Misconceptions About Running Back Speed
Fans frequently misinterpret athletic testing numbers, leading to unrealistic expectations on Sundays.
- The Myth of Open-Field Speed vs. Functional Speed: A 4.48 time doesn't mean a player will outrun every secondary defender from 50 yards out. Functional speed on a football field involves pads, vision, and fatigue. Judkins relies on game speed—accelerating rapidly through small windows—rather than track speed.
- Weighing Combine Times Heavily Over Tape: Metrics should confirm film study, not replace it. If a prospect looks slow on tape, a fast combine time is an anomaly; if a prospect looks dominant on film and tests well like Judkins did, it removes athletic ceiling concerns.
