LOS ANGELES — When Tyriq McCord joined NASCAR as a pit crew member a little more than three years ago, his knowledge of what made a car go fast stopped and started with the gas pedal.
"I didn't even know how to change the tire on my car," he said.
But he could bench-press 225 pounds and run 40 yards in 4.5 seconds and those were the kinds of skills Phil Horton was looking for.
