How the NFL Combine Measures Explosiveness (And Why It Matters) When people think of the Combine, they think of speed and highlights… But what teams are really evaluating is explosiveness — how fast and how powerfully you can produce force. And the truth is… these tests apply to every athlete, not just skill positions. 1. Vertical Jump What it is: Standing jump straight up, measuring how high you can elevate. What it measures: Lower-body power — how quickly you can produce force vertically. Why it matters: This is pure explosion. No steps. No rhythm. Just you generating force from nothing. If you can’t create force fast, you can’t: - Drive off the line - Explode out of movements - Generate power in contact situations 2. Broad Jump What it is: Standing jump forward for distance. What it measures: Horizontal power — your ability to project force forward. Why it matters: Sports aren’t played straight up and down. They’re played forward. This shows how well you: - Accelerate - Cover ground - Transfer strength into movement 3. 40-Yard Dash (First 10 Yards Matter Most) What it is: Sprint over 40 yards, with heavy focus on the first 10 yards. What it measures: Acceleration and force application into the ground. Why it matters: Most sports moments happen in the first few steps. This tells coaches: - How quickly you can get moving - How efficiently you apply force - How explosive your start is 4. 3-Cone Drill What it is: A tight change-of-direction drill around three cones. What it measures: Deceleration and re-acceleration ability. Why it matters: Explosiveness isn’t just going fast… It’s stopping, redirecting, and exploding again. This shows: - Body control - Elastic strength - Ability to produce force at different angles 5. 20-Yard Shuttle (5-10-5) What it is: Sprint 5 yards, change direction, go 10 yards, then back 5. What it measures: Lateral explosiveness and reactive power. Why it matters: Most athletes struggle changing direction, not running straight.
