THURSDAYS 6PM/ET ON

ALL JAMAAL

Chiefs running back Jamaal Charles has accounted for a league-high 35% of his team’s yards from scrimmage (through Week 11), nearly 5% more than anyone else. We turned to ESPN Sport Science to find out what makes the workhorse run.

THE MOST FUEL-EFFICIENT V-8 IN A PICKUP.* Best 100-meter time Charles ran at Texas. It would have met the 2012 U.S. Olympic qualifying standard.

DIRECT INJECTION For precise fuel distribution and fast, efficient combustion. ACTIVE FUEL MANAGEMENT By sensing load and demand, it improves efficiency by activating or deactivating cylinders. VARIABLE VALVE TIMING For responsiveness in low-speed city driving and bold power for open-road passing or trailering.

Number of g’s Charles experiences exploding out of a cut. The average RB cuts with about 3 g’s, equivalent to what astronauts experience during shuttle launches.

ALL-NEW GMC SIERRA *EPA-estimated mpg 16 city/23 hwy (2WD); 16 city/22 hwy (4WD) with the available 5.3L V-8.

Peak power, in watts, Charles can generate in a single burst. That’s enough wattage to power a lighthouse.

2,000

Speed, in mph, Charles can reach on the field. By comparison, Sport Science tracked Adrian Peterson at a top speed of 21.8 mph this year.

630,000 Estimated cumulative pounds of force Charles will feel while being tackled this season, based on a conservative estimate of 350 tackles at 1,800 pounds of force per tackle. That’s comparable to being kicked by a horse more than 200 times.

Seconds it took Charles to complete the Game Changer Test, requiring three sharp cuts as fast as possible. He’s the fastest-cutting athlete Sport Science has ever tested.
