If you’ve spent any time on Michigan message boards lately, you know the hype around Bryce Underwood is bordering on mythological. We’re talking about a kid who was the consensus No. 1 recruit in the country, a 6-foot-4, 230-pound statue of a quarterback who somehow moves like a gazelle. Naturally, everyone wants to know the numbers. Specifically, everyone is obsessed with the Bryce Underwood 40 time.
Is he a burner? Not exactly in the Tyreek Hill sense. But for a guy who looks like he was built in a lab to play Sunday football, the speed is plenty real.
Most reliable scouting reports and verified recruiting data have the Bryce Underwood 40 time clocked at a crisp 4.58 seconds. Now, pause for a second. If you’re a casual fan, 4.58 might just sound like a "good" number. But in the context of a 230-pound quarterback? That’s moving. To put that in perspective, J.J. McCarthy—who was plenty mobile for the Wolverines—arrived on campus with a 4.89 before eventually shaving that down. Underwood is starting his college career already faster than most veteran signal-callers.
Breaking Down the Bryce Underwood 40 Time
Let's be honest: 40 times are often inflated in high school. We’ve all heard of the "hand-timed" 4.4 that magically becomes a 4.65 at the NFL Combine. However, Underwood's athleticism isn't just a track number; it’s functional. During his senior year at Belleville High School, he didn't just stand in the pocket and pick teams apart with that cannon arm. He ran for over 600 yards and six touchdowns. He wasn't just falling forward for three yards, either. He was outrunning defensive backs to the pylon.
The "Vince Young" Comparison
It's a big name to drop. Maybe too big. But 247Sports and various scouts have frequently pointed to Vince Young as the physical blueprint for Underwood. When you watch the film, you see why. He has these long strides that eat up five yards before the linebacker even realizes he's tucked the ball.

A 4.58 40-yard dash means that if a lane opens up in the B-gap, he's gone. He’s not a "scrambler" who panics and runs; he’s a vertical mover. He navigates pressure with this weirdly calm pocket presence and then—boom—he’s twenty yards downfield because the defense forgot he has wheels.
Is He Actually a Dual-Threat?
This is where things get interesting. If you look at his freshman season stats at Michigan—particularly those early games against New Mexico and Oklahoma—the rushing numbers weren't always mind-blowing. Against the Sooners, he actually finished with negative rushing yardage. Does that mean the Bryce Underwood 40 time is a lie?
Hardly.
It’s about coaching. Under Sherrone Moore and offensive coordinator Chip Lindsey, the goal has clearly been to protect the "franchise." You don't take the No. 1 recruit in the world and run him into the teeth of an SEC-caliber defense 20 times a game. Not in year one.

- High School Production: 1,400+ rushing yards over his career.
- Physicality: He’s 230 lbs. He doesn't slide as much as he should; he finishes runs.
- The "Juice": In the Michigan Spring Game, coaches repeatedly noted his "juice" in the open field.
Basically, the speed is a tool in the toolbox, not the whole hardware store. He’s a passer first. A passer with a 4.58 40 time is a nightmare for defensive coordinators because you can’t just play "man" coverage and turn your back to him. He’ll kill you.
Why the Speed Matters for the 2026 Season
Looking ahead to 2026, the Bryce Underwood 40 time is going to become even more relevant as the playbook expands. Now that he has a full year of Big Ten hits under his belt, expect the "guardrails" to come off.
We saw flashes of it against Central Michigan where he ripped off a 114-yard rushing performance. That’s the ceiling. When the play breaks down and the pocket collapses, Underwood has the recovery speed to turn a 10-yard loss into a 30-yard highlight.
Scouts from the next level are already salivating. Usually, you get the "big arm" guy or the "fast" guy. Underwood is the rare crossover. He has 10-inch hands, can throw a frozen rope 60 yards, and still beats your nickel corner in a footrace.

What People Get Wrong About QB Speed
A lot of fans think a "fast" QB needs to be Lamar Jackson. That’s not Underwood. He’s more in the Josh Allen or Cam Newton mold. It’s "heavy" speed. When he hits 20 mph, he’s a freight train.
Honestly, the obsession with the Bryce Underwood 40 time is kind of funny when you realize he’s also one of the most cerebral young QBs we’ve seen. He’s reading Cover 3 shells and layering balls over linebackers like a five-year pro. The fact that he can also run a sub-4.6 is just an unfair bonus.
Actionable Insights for Fans and Scouts
If you're tracking Underwood's development into the 2026 season, keep an eye on these specific markers rather than just the stopwatch:
- Designed Runs: Watch how many times Michigan calls his number on the read-option. If that number goes up, it means they trust his speed to handle the edge.
- Scramble Efficiency: Does he gain yards when the play breaks down, or does he just throw it away? His 40-time suggests he should be a 500+ yard rusher annually.
- Weight Management: If he climbs to 240 or 245 lbs, that 4.58 might dip to a 4.65, but he’ll be harder to bring down. It's a trade-off.
Ultimately, the kid is a freak. Whether he's running a 4.58 or a 4.62, the reality is that Bryce Underwood is the most athletic person on the field 90% of the time. For Michigan fans, that’s a very good place to be.
Next Step: Watch his highlight reel from the 2025 game against Texas. Pay attention to his 33-yard scramble in the fourth quarter. It’s the perfect example of how his 40-yard speed actually translates to "game speed" when the lights are brightest.
