Knowshon Moreno
He may be retired now, but Knowshown Moreno had quite a career as a running back. He played for the Miami Dolphins and the Denver Broncos, which must have been a childhood dream come true. Growing up, Moreno probably had no idea that his net worth would be in the millions one day.

Moreno’s parents were just teenagers when he was born, and they were unable to take care of him and provide him with a stable environment. He grew up living in various homeless shelters and was eventually adopted by his grandparents. He still reflects on his past and how it led to where he is now. Whenever “The Star-Spangled Banner” would play before a game, Moreno said, “I run through my whole life right there at that moment. Even the bad stuff.”
