The NFL Combine is a spectacle of numbers: 40-yard dash times, vertical leaps, arm length, hand size, and bench press reps. Every year, analysts pour over these stats, trying to predict which prospects will become stars. But here’s the reality: while measurements provide insight, they don’t define a player’s success.
Some athletes check every box physically but never make an impact in the league. Others are labeled “too small” or “not quite right” and go on to become game-changers. The real difference-makers in football aren’t defined by measurements—they’re built on skill, instinct, and determination.
Size Matters—Until It Doesn’t
Take LSU offensive tackle Will Campbell. He has everything scouts look for—except one thing: the standard 33-inch arm length for tackles.
That number alone might cause some evaluators to question his ability to fend off elite edge rushers. But should it?
Look at Penei Sewell. His arms fall short of the “ideal” length for a tackle, yet he’s an All-Pro right tackle. His footwork, strength, and intelligence make him elite, proving that talent trumps tape-measure numbers.
The game isn’t played in a lab, it’s played on the field.
The Quarterback Numbers Game
Quarterbacks might be the most overanalyzed position when it comes to measurements. Scouts scrutinize everything, even something as specific as hand size, believing it impacts grip and throwing ability. But history tells a different story:
Joe Burrow’s hands? Exactly nine inches, placing him in the bottom 10th percentile among QBs. Did that stop him? No. He led his team to a Super Bowl appearance.
Patrick Mahomes? His hands measure 9 1/4 inches, right in the middle of the pack. Does that define his greatness? Not at all, he’s one of the most dominant quarterbacks in the game today.
The best quarterbacks succeed because of accuracy, decision-making, and leadership—not because of an extra fraction of an inch on their hands.
Enhance Player Safety with Atavus Tacklytics
Reduce missed tackles and improve performance through data-driven analysis.
Wide receivers face the same scrutiny when it comes to arm length and wingspan. The assumption? A bigger catch radius means a better receiver. But success in the NFL isn’t that simple.
Brian Thomas Jr. has a massive wingspan, which certainly helps him make highlight-reel catches. But that’s just one piece of his game.
Ladd McConkey? His arm length is below average, yet he still put up over 1,100 receiving yards. His elite route running and understanding of defenses allowed him to carve up secondaries all season./span>
It’s not just about reach—it’s about how you use it.
The Truth About the Combine
The Combine is a useful tool, but it’s not a crystal ball.
Some players dominate the event but struggle when the pads go on. Others don’t meet the “ideal” measurements yet thrive at the next level. The key? Game tape, skill, and mindset matter far more than arm length or hand size.
The NFL isn’t played on a spreadsheet. It’s played between the lines.
