ABERDEEN, Md. -- Erin Henderson pulled up in a silver 2000 Lincoln Navigator, his old high school ride -- a gift from his older brother, E.J., who bought it with his first NFL signing bonus in 2003. Henderson had just come from his day job as a substitute eighth-grade math teacher, and he was in a rush to make it to the next part of his day.
In the driver's seat, Henderson changed out of his buttoned-down blue Polo shirt, brown slacks and brown dress shoes. He slipped into his other work clothes -- a gray Under Armour T-shirt, baggy black shorts and sneakers.
