There's a sound the human body makes when it's properly pancaked.
It isn't as loud or pronounced as one might expect, but when a man—or in this instance, a teenager—weighing in excess of 300 pounds plants his weight and momentum purposefully on an opponent, it is distinct.
"There's this big huff of breath," says Bryce Foster, a 17-year-old with ample experience. "And all you can hear is their soul leaving their body."
You can hear him smile through the phone. Hear his pride and playfulness. While some take pride in touchdowns and yardage and other stats like that, Foster takes pride in something else.
